depression:have you experience it?

I haven't felt any deep depression on my entire life. But there were times that I felt depressed and frustrated at the same time. During those times I kept crying and kept asking help from God. I know He will help me and everything will be fine.

Like you everyone experiences times when they are unhappy. Sometimes this is because of a loss, or a change. It hurts a lot at times. The feeling of sadness, though, is appropriate and transitory. When such feelings persist and impair daily life, they may signal an underlying depressive illness. This is a difficult situation to handle. So it is the severity and duration of symptoms, plus the presence of other features, that help distinguish this normal sadness from a depressive disorder. I have a doctor friend who treats depression and is really the one I look forward to seek advice on such matters.
