Have you read DR? It's really good, and explains it well.
I think a lot of us here have had/have depression. What we go through/have gone through is so stressful; I think it's almost unnatural if we don't get depressed.

Keep posting here. Ask questions, vent or whatever. This site has been a lifeline for me definitely...
