Depression is not the same as having occasional "blues" or feeling sad every once in a while and then bouncing back to your old self. Depression can be mild, moderate, or so bad that it affects every part of your life - your body, your feelings, your thoughts, and your behaviors. It can impact your family relationships, your friendships, and your ability to work, play, or just get through your day. Depression can even make you feel like you don't want to live.

About two-thirds of people who are depressed think that life's not worth living. These thoughts and feelings aren't your fault - they can be part of depression. Some studies suggest that between 10% and 15% of people with depression commit suicide. Treatment can help prevent suicide. Depression is an illness, and your feelings can and will change with treatment.
