Is there any way to fight depression without taking antidepressants?

DEPENDS: It really depends on the severity of the depression. We are talking about the disease of depression and not just the transient emotion. If mild you may consider therapy. Also exercise and good sleep and eating habits can help. If moderate to severe the best treatment is medication and therapy. Talk to your physician to help decide the best approach but do not wait for it to get out of hand.

Depression: Psychotherapy helps, especially cognitive behavior tx, social skills training, grief work, and group therapy.

Natural aids: Exercise is a natural antidepressant. Even when you feel like staying in bed, get up and exercise. It will improve your mood. Laughter is also a natural antidepressant. See a funny movie. Laugh out loud. Speak with a friend. Go to a mall, it may help you get your mind off your troubles. Listen to music it may also help improve your mood. Therapy is also a huge help so why not take advantage of it?
