Feeling sad after a disappointment, loss, or difficult week is a normal part of life. Depression is different. Clinical depression can affect how you feel, think, sleep, eat, work, and interact with other people. Symptoms may develop gradually, which means someone can become accustomed to feeling unwell without realizing how much their daily life has changed.

Major depression typically involves a depressed mood or loss of interest that persists most of the day, nearly every day, for at least two weeks and interferes with normal activities. However, you do not need to wait exactly two weeks to seek help—especially when symptoms are severe, rapidly worsening, or involve thoughts of self-harm.

Depression can look different from one person to another. Some people appear visibly sad, while others become irritable, exhausted, withdrawn, physically uncomfortable, or unable to enjoy anything. Here are 14 symptoms that deserve attention—and practical steps to take when you recognize them.

 

 

Get immediate support during a crisis

If you are thinking about suicide, harming yourself, or feel unable to stay safe, call or text 988 in the United States to reach the Suicide & Crisis Lifeline.

Call 911 or go to the nearest emergency department when there is an immediate danger.

You can also contact 988 when you are worried about a friend or family member. Warning signs are especially concerning when they are new, becoming more intense, or appear after a painful event, major loss, or sudden life change.

 

1. Persistent sadness, emptiness, or emotional heaviness

One of the most recognized signs of depression is a sad, anxious, or “empty” mood that does not seem to lift.

This may feel like:

• A constant emotional weight
• Frequent crying
• Feeling emotionally numb
• Waking up with a sense of dread
• Feeling low even when nothing specific has happened
• Being unable to imagine feeling better

Not everyone with depression cries or appears visibly upset. Some people describe the experience as feeling disconnected, emotionally flat, or as though they are simply going through the motions.

What to do

Begin tracking how you feel each day. Record when the sadness began, whether it changes during the day, and how it affects your routine.

Contact a primary care professional or mental health provider when the feeling persists, repeatedly returns, or interferes with work, relationships, sleep, eating, or self-care.

 

2. Losing interest in things you once enjoyed

A major warning sign is losing interest or pleasure in activities that previously felt enjoyable or meaningful. This symptom is sometimes called anhedonia.

You may notice that you no longer enjoy:

• Hobbies
• Exercise
• Music
• Social events
• Cooking
• Spending time with family
• Intimacy
• Television, games, or books
• Activities you used to look forward to

You might continue doing these things out of habit but feel little emotional response.

Loss of interest is one of the central symptoms used when evaluating depression.

What to do

Do not wait for motivation to return before taking every action. Choose one small activity and reduce it to a manageable level.

For example:

• Listen to one song instead of an entire album.
• Walk for five minutes instead of completing a full workout.
• Text one person instead of attending a large gathering.
• Spend five minutes on a hobby.

This does not replace treatment, but maintaining some contact with meaningful activities may help prevent further withdrawal.

 

3. Feelings of hopelessness or pessimism

Depression can change the way a person imagines the future. Temporary problems may begin to feel permanent, and realistic possibilities can become difficult to see.

Thoughts may include:

• “Nothing will ever improve.”
• “There is no point in trying.”
• “My future is ruined.”
• “I will always feel this way.”
• “Treatment will not work for me.”
• “Everyone would be better without me.”

Hopelessness deserves serious attention because it can increase the risk that someone stops seeking help or begins thinking about death.

What to do

Tell another person clearly what you are experiencing. Instead of saying only that you feel stressed, try:

“I have been feeling hopeless, and I’m having trouble imagining things getting better.”

Contact a healthcare professional promptly. Call or text 988 when hopelessness is accompanied by thoughts of dying, disappearing, self-harm, or being a burden.

 

4. Irritability, frustration, or unusual anger

Depression does not always look like sadness. In some people, it appears primarily as:

• Irritability
• Restlessness
• Impatience
• Angry outbursts
• Frequent arguments
• Becoming overwhelmed by small problems
• Feeling constantly “on edge”

Friends or relatives may notice a personality change before the person recognizes depression.

Irritability and restlessness are both recognized symptoms associated with depression.

What to do

Pay attention to whether the irritability is new, unusually intense, or accompanied by changes in sleep, appetite, motivation, or enjoyment.

Avoid using alcohol or other substances to calm down. Step away from escalating conflicts and arrange an appointment with a healthcare professional when anger is affecting relationships, work, or safety.

 

5. Feeling worthless, guilty, or like a burden

Depression can create an excessively negative view of oneself.

A person may believe:

• They are failing everyone.
• They do not deserve help.
• They are responsible for things outside their control.
• Their family would be better without them.
• Small mistakes prove that they are a bad person.
• They have no value unless they are productive.

This is different from taking reasonable responsibility for a mistake. Depressive guilt is often excessive, persistent, and disconnected from the actual situation.

What to do

Write the thought down and ask:

• What evidence supports this belief?
• What evidence does not support it?
• Would I say this to someone I care about?
• Is depression presenting an opinion as though it were a fact?

Share these thoughts with a doctor or therapist. Feeling like a burden can also be a suicide warning sign, particularly when combined with hopelessness, withdrawal, or talk about death.

 

6. Constant fatigue or lack of energy

Depression can make ordinary activities feel physically exhausting.

You may experience:

• Difficulty getting out of bed
• Feeling tired after adequate sleep
• Needing frequent breaks
• Struggling to shower or prepare food
• Losing the energy to answer messages
• Feeling as though your body is unusually heavy
• Becoming exhausted by simple decisions

Fatigue and low energy are common symptoms of depression, but they can also occur with anemia, thyroid disorders, sleep apnea, vitamin deficiencies, infections, medication side effects, and other medical conditions.

What to do

Schedule a medical evaluation rather than assuming the cause is purely psychological. A clinician may review your symptoms, medications, sleep quality, diet, and relevant medical conditions.

While waiting for care, divide necessary tasks into smaller steps. “Take a shower” may become:

1. Sit up.
2. Put your feet on the floor.
3. Walk to the bathroom.
4. Turn on the water.
5. Take a brief shower.

Making a task smaller is not laziness. It is a practical response to reduced energy.

 

7. Sleeping too little, waking early, or sleeping too much

Depression can disrupt sleep in several ways.

Some people experience:

• Difficulty falling asleep
• Waking repeatedly during the night
• Waking hours earlier than planned
• Sleeping for long periods
• Staying in bed most of the day
• Feeling exhausted regardless of sleep duration

Sleep problems can worsen mood, concentration, energy, and emotional regulation. They may also reflect a separate sleep disorder.

What to do

Keep a consistent wake-up time, reduce bright screens near bedtime, limit caffeine later in the day, and discuss persistent sleep changes with a healthcare professional.

Seek medical evaluation if you snore loudly, gasp during sleep, wake with headaches, or experience severe daytime sleepiness, as these can be signs of sleep apnea or another sleep disorder.

Do not use alcohol as a sleep aid. It can disrupt sleep quality and may worsen depression.

 

8. Significant appetite or weight changes

Depression may cause someone to eat much less or much more than usual.

Possible changes include:

• Having little interest in food
• Forgetting to eat
• Feeling nauseated around meals
• Eating mainly for comfort
• Craving sweets or refined carbohydrates
• Eating late at night
• Unplanned weight loss
• Unplanned weight gain

Changes in appetite and weight are recognized symptoms, particularly when they represent a clear change from the person’s usual behavior.

What to do

Focus first on regular nourishment rather than creating a perfect diet. Easy options may include:

• Yogurt and fruit
• Eggs and toast
• Soup
• Frozen vegetables
• Beans and microwaveable rice
• Peanut butter sandwiches
• Rotisserie chicken
• Smoothies
• Precut fruit
• Ready-to-eat salads

Contact a medical professional when appetite changes are substantial, weight changes are unexplained, eating feels impossible, or food is being used in a way that causes distress.

 

9. Difficulty concentrating, remembering, or making decisions

Depression can interfere with cognitive function. Tasks that once felt easy may become unexpectedly difficult.

You may notice:

• Reading the same sentence repeatedly
• Forgetting appointments
• Losing track of conversations
• Struggling to complete work
• Becoming overwhelmed by simple choices
• Difficulty organizing tasks
• Feeling mentally slowed down
• Making more mistakes than usual

Concentration, memory, and decision-making difficulties are established symptoms of depression.

What to do

Reduce unnecessary decisions and externalize important information.

Try:

• Writing a short daily list
• Using calendar reminders
• Completing one task at a time
• Breaking projects into 10-minute sessions
• Asking for written instructions
• Postponing major decisions when possible

Sudden confusion, speech difficulty, weakness, severe headache, or rapid cognitive changes require urgent medical evaluation because they may have causes unrelated to depression.

 

10. Moving, speaking, or thinking unusually slowly

Depression can cause noticeable slowing of movement, speech, or thought. This is sometimes described as psychomotor slowing.

Signs may include:

• Speaking more slowly
• Taking a long time to answer
• Walking more slowly
• Reduced facial expression
• Sitting motionless for extended periods
• Feeling as though thoughts are moving through fog
• Needing much longer to complete simple tasks

The opposite can also happen. Some people become restless, fidgety, or unable to sit still. Both slowing and agitation can occur with depression.

What to do

Ask someone you trust whether they have noticed a change. Contact a healthcare professional promptly when the slowing or agitation is significant.

Urgent evaluation may be necessary if someone is barely speaking, not eating or drinking, unable to care for themselves, extremely agitated, or disconnected from reality.

 

11. Unexplained aches, headaches, or digestive problems

Depression can be associated with physical symptoms, including:

• Headaches
• Back pain
• Muscle aches
• Stomach discomfort
• Digestive changes
• Chest tightness
• General bodily pain

These symptoms are real. They should not automatically be dismissed as “all in your head.”

The CDC includes aches, pains, headaches, and stomach problems that do not improve with treatment among possible symptoms associated with depression.

What to do

Discuss persistent or unexplained physical symptoms with a medical professional. The goal is to evaluate both physical and mental health rather than assuming one explanation.

Seek emergency care for severe chest pain, trouble breathing, fainting, sudden weakness, a sudden severe headache, or other potentially urgent symptoms.

 

12. Withdrawing from friends, family, and everyday activities

A person with depression may:

• Stop answering calls
• Cancel plans repeatedly
• Avoid family members
• Stop attending school, work, church, or community activities
• Spend most of the day alone
• Feel exhausted by conversation
• Believe other people do not want them around

Withdrawal can provide temporary relief from social demands, but prolonged isolation may deepen depression and make it harder for others to recognize that help is needed.

What to do

Choose the lowest-pressure form of connection available.

For example:

• Send a brief text.
• Sit in the same room as another person.
• Ask someone to take a short walk.
• Schedule a phone call.
• Work in a public library or café.
• Join a moderated support group.

You do not have to explain everything. A message can be as simple as:

“I’ve been isolating because I haven’t been feeling well. Could you check in with me this week?”

 

13. Using more alcohol, cannabis, or other substances

Some people attempt to manage depression by drinking, using cannabis, misusing medication, or using other substances.

They may be trying to:

• Fall asleep
• Stop thinking
• Feel temporarily numb
• Reduce social anxiety
• Escape emotional pain
• Create enough energy to function

Although substances may provide short-term relief, they can worsen sleep, mood instability, impulsivity, relationships, and treatment adherence. Increased substance use can also be a sign that someone needs professional support.

What to do

Tell a doctor or therapist honestly what you are using, how often, and why. This information helps them recommend safer and more effective care.

Do not abruptly stop heavy daily alcohol or sedative use without medical guidance. Withdrawal can be dangerous.

For treatment and referral information in the United States, contact SAMHSA’s National Helpline at 1-800-662-HELP (4357).

 

14. Thoughts about death, suicide, or self-harm

Thoughts of death or suicide are among the most urgent signs of depression.

They may be direct:

• “I want to die.”
• “I’m going to hurt myself.”
• “I’m thinking about suicide.”

They may also be indirect:

• “I wish I would not wake up.”
• “Everyone would be better without me.”
• “There is no reason for me to be here.”
• “Soon you won’t have to worry about me.”
• “I can’t do this anymore.”

Other warning signs can include giving away important possessions, saying goodbye unexpectedly, looking for methods, making final arrangements, taking unusual risks, or displaying a sudden change in mood after intense distress.

What to do

Take every mention of suicide seriously.

When you are concerned about someone, ask directly:

“Are you thinking about suicide?”

Asking clearly does not create suicidal thoughts. It can open the door to an honest conversation and immediate help.

If the answer is yes:

• Stay with the person or remain connected by phone.
• Call or text 988.
• Reduce access to firearms, medications, or other potentially lethal means when you can do so safely.
• Do not promise to keep suicidal thoughts secret.
• Contact emergency services if there is an immediate threat.
• Follow up after the crisis.

When you are the person experiencing these thoughts, move away from anything you could use to harm yourself and contact 988, emergency services, or a trusted person immediately.

 

What to do when you recognize several symptoms

Recognizing symptoms does not mean you should diagnose yourself. It means you have enough reason to seek an appropriate evaluation.

1. Record what has changed

Write down:

• When the symptoms began
• How often they occur
• Whether they are getting worse
• How your sleep and appetite have changed
• Whether work or relationships are being affected
• Any new medications or supplements
• Alcohol or substance use
• Recent illness, loss, pregnancy, childbirth, menopause, or major stress
• Any thoughts of death or self-harm

This information can make a medical appointment more productive.

2. Make an appointment

You can begin with:

• A primary care doctor
• A licensed therapist
• A psychiatrist
• A community mental health center
• A telehealth provider
• An employee assistance program
• A school or university counselor

A primary care clinician can assess symptoms, review medications, consider medical causes, and provide a referral when needed.

3. Tell someone you trust

Depression often becomes harder to manage in secrecy.

Consider saying:

“I think I may be experiencing depression. I need help scheduling an appointment and staying connected.”

Ask for a specific form of support, such as transportation, help making a phone call, company during an appointment, or a daily check-in.

4. Avoid making major decisions during a severe episode

When possible, postpone irreversible decisions involving relationships, employment, finances, housing, or other major life changes until your symptoms have been evaluated.

Depression can make the future appear more hopeless and options more limited than they actually are.

5. Support basic daily needs

While arranging professional care, focus on basic structure:

• Get out of bed at a consistent time.
• Eat simple, regular meals.
• Drink water.
• Take prescribed medication as directed.
• Get a small amount of daylight.
• Move your body gently.
• Avoid isolation.
• Reduce alcohol and recreational drug use.
• Create distance from anything you might use for self-harm.

These steps are supportive. They are not substitutes for professional treatment.

How depression is treated

Depression is treatable. Depending on the individual, treatment may include:

• Psychotherapy
• Antidepressant medication
• A combination of therapy and medication
• Treatment of related sleep or medical conditions
• Support for alcohol or substance use
• Lifestyle changes
• More intensive treatment for severe or treatment-resistant depression

Finding the right treatment may take time. Needing to adjust a medication, change therapists, or try a different approach does not mean recovery is impossible.

NIMH notes that depression treatment commonly includes psychotherapy, medication, or both.

Symptoms that may suggest something other than unipolar depression

Tell a healthcare professional if depressive periods alternate with episodes involving:

• Unusually high or irritable mood
• Very little need for sleep
• Racing thoughts
• Rapid speech
• Uncharacteristic confidence
• Increased energy
• Reckless spending
• Risky sexual behavior
• Impulsive decisions

These symptoms may be associated with bipolar disorder. Bipolar depression can resemble major depression, but treatment decisions may differ, making an accurate evaluation important.

Hallucinations, paranoia, extreme confusion, inability to care for basic needs, or losing contact with reality also require prompt professional assessment.

Frequently asked questions

How many symptoms are needed for a depression diagnosis?

A diagnosis cannot be made from one symptom or an online checklist. Clinicians consider the number, duration, severity, pattern, and impact of symptoms, along with possible medical or substance-related causes.

Persistent depressed mood or loss of interest lasting approximately two weeks is an important indicator, but urgent symptoms should be addressed immediately rather than waiting for a specific duration.

Can someone be depressed without looking sad?

Yes. A person may continue working, caring for family, smiling, or appearing socially engaged while privately experiencing hopelessness, exhaustion, numbness, or suicidal thoughts.

Others may primarily show irritability, physical pain, substance use, sleep disruption, or withdrawal.

Can physical illness cause symptoms that resemble depression?

Yes. Thyroid problems, anemia, sleep disorders, chronic pain, hormonal changes, medication side effects, nutritional deficiencies, neurological conditions, and other medical issues can contribute to depressive symptoms.

A medical evaluation can help identify or rule out contributing factors.

Is depression a normal part of aging?

No. Older adults may experience losses, medical challenges, reduced mobility, or isolation, but depression is not an inevitable or normal part of aging. It is a treatable condition that deserves medical attention.

What should I say to someone who may be depressed?

Use direct, nonjudgmental language:

“I’ve noticed you haven’t seemed like yourself lately. How have you been feeling?”

You can also ask:

“Are you feeling hopeless?”

“Are you thinking about hurting yourself?”

Listen without immediately arguing, minimizing, comparing experiences, or offering simplistic advice.

Avoid statements such as:

• “Just think positively.”
• “Other people have it worse.”
• “You have nothing to be depressed about.”
• “You need to be stronger.”
• “You should be grateful.”

Offer a specific next step:

“Can I sit with you while we call a doctor or 988?”

The bottom line

Depression is more than sadness. It can affect emotion, thinking, energy, sleep, appetite, movement, physical comfort, relationships, substance use, and a person’s ability to imagine a future.

Pay particular attention when symptoms:

• Last for approximately two weeks
• Appear nearly every day
• Become more intense
• Interfere with daily functioning
• Cause major personality or behavior changes
• Lead to isolation or increased substance use
• Include hopelessness, self-harm, or thoughts of death

You do not need to be certain that you have depression before asking for help. Recognizing that something has changed is enough reason to speak with a healthcare professional.

When thoughts of suicide or self-harm are present, call or text 988 in the United States. Call 911 when there is an immediate danger.
