What is depression?
Key symptoms of depression that are present most of the day, nearly every day, for at least two weeks are:
- Depressed mood and/or
- Greatly reduced interest or pleasure in most activities
In addition, several of these symptoms are present nearly every day. Not everyone with depression has all of these symptoms:

- Decrease or increase in appetite compared to usual
- Sleeping much less or much more than usual
- Problems concentrating or making decisions
- Feeling very tired and weak or very low on energy
- Feeling worthless or guilty (not just guilt about feeling depressed)
- Feeling restless or slowed down – so much that other people notice it
- Family members or friends notice that you are not your usual self and that your mood is low
- Thinking a lot about suicide and/or death (not just fear of death)
Other common experiences are:
- Increased irritability
- Decreased motivation
- Feeling less interested in sex
Depression becomes more common during the teenage years and is especially common in young adult years when people are going through many life changes. Twice as many women as men report problems with depression. It is a common problem throughout the adult years.
People who are having problems with depression often have other problems at the same time such as anxiety (nervousness, fears, worries) or problems with excessive use of alcohol or drugs.
Who can give advice?
- Many people are familiar with depression and willing to guide you to get whatever help you may need.
- It can be difficult to speak to someone about personal problems, but your family doctor, another health care provider, a school counselor, someone with the Mood Disorders Association, or a telephone help line can help.
