I feel your pain, dude. I'm in a similar situation (I'd post it here but I don't want to look like I'm stealing sympathy or start a new thread about my personal problems) and it does suck. I think it's regular, because most men our age group (late teens - mid/late twenties) are the most likely to commit suicide, so that definitely means that we are more succeptable to depression. I know how it feels thinking that all your friends are doing better than you, and that you're not amounting to anything. I've come to the assumption that if my life was a basketball game, I'd be a good team that was down by 8 and getting horrible calls. 
  
Eventually though everything will be better. I keep telling myself that. And you should to.
