Depression

I know this sounds dumb and I don't want to sound like that ignorant college kid but I am taking a class right now on mental disorders and we are getting ready to start a section on depression. I found it was ironic that this thread popped up the week before we started it. If I learn anything that could be of any help I will def. let you guys know and if you have any questions I'll see what I can do. I had no idea depression effected so many people.
