I've been depressed for about half my life. I use to be motivated to the extreme and now i'm not movtivated to do anything. The problem is I can't figure out how I went from hard working to doing absolutley nothing. I was happy when I was really young but now i'm not. How do I figure out what changed me? Is it possible to change back? I was reading the depression FAQ thing and it said that once your depressed its hard to change because the saratonin levels in your brain really decrease.
