Although depression may occur only one time during your life, usually people have multiple episodes of depression. During these episodes, symptoms occur most of the day, nearly every day and may include:

  • Feelings of sadness, tearfulness, emptiness or hopelessness
  • Angry outbursts, irritability or frustration, even over small matters
  • Loss of interest or pleasure in most or all normal activities, such as sex, hobbies or sports
  • Sleep disturbances, including insomnia or sleeping too much
  • Tiredness and lack of energy, so even small tasks take extra effort
  • Changes in appetite — often reduced appetite and weight loss, but increased cravings for food and weight gain in some people
  • Anxiety, agitation or restlessness
  • Slowed thinking, speaking or body movements
  • Feelings of worthlessness or guilt, fixating on past failures or blaming yourself for things that aren't your responsibility
  • Trouble thinking, concentrating, making decisions and remembering things
  • Frequent or recurrent thoughts of death, suicidal thoughts, suicide attempts or suicide
  • Unexplained physical problems, such as back pain or headaches

For many people with depression, symptoms usually are severe enough to cause noticeable problems in day-to-day activities, such as work, school, social activities or relationships with others. Other people may feel generally miserable or unhappy without really knowing why.

Depression symptoms in children and teens

Common signs and symptoms of depression in children and teenagers are similar to those of adults, but there can be some differences.

  • In younger children, symptoms of depression may include sadness, irritability, clinginess, worry, aches and pains, refusing to go to school, or being underweight.
  • In teens, symptoms may include sadness, irritability, feeling negative and worthless, anger, poor performance or poor attendance at school, feeling misunderstood and extremely sensitive, using drugs or alcohol, eating or sleeping too much, self-harm, loss of interest in normal activities, and avoidance of social interaction.

Children with attention-deficit/hyperactivity disorder (ADHD) can demonstrate irritability without sadness or loss of interest. However, major depression can occur with ADHD.

Depression symptoms in older adults

Depression is not a normal part of growing older, and it should never be taken lightly. Unfortunately, depression often goes undiagnosed and untreated in older adults, and they may feel reluctant to seek help. Symptoms of depression may be different or less obvious in older adults, such as:

  • Memory difficulties or personality changes
  • Physical aches or pain
  • Fatigue, loss of appetite, sleep problems, aches or loss of interest in sex — not caused by a medical condition or medication
  • Often wanting to stay at home, rather than going out to socialize or doing new things
  • Suicidal thinking or feelings, especially in older men

When to see a doctor

If you feel depressed, make an appointment to see your doctor as soon as you can. If you're reluctant to seek treatment, talk to a friend or loved one, a health care professional, a faith leader, or someone else you trust.

When to get emergency help

If you think you may hurt yourself or attempt suicide, call 911 or your local emergency number immediately.

Also consider these options if you're having suicidal thoughts:

  • Call your mental health specialist.
  • Call a suicide hotline number — in the U.S., call the National Suicide Prevention Lifeline at 1-800-273-TALK (1-800-273-8255). Use that same number and press "1" to reach the Veterans Crisis Line.
  • Seek help from your primary doctor or other health care provider.
  • Reach out to a close friend or loved one.
  • Contact a minister, spiritual leader or someone else in your faith community.

If a loved one or friend is in danger of attempting suicide or has made an attempt:

  • Make sure someone stays with that person
  • Call 911 or your local emergency number immediately
  • Or, if you can do so safely, take the person to the nearest hospital emergency room
