Lifesnotfair- I guarantee you haven't tried "everything under the sun". You may have tried a lot of different stuff, seen many different people, but that doesn't mean you're incurable or can't be helped. I'm no psycologist (although I'm studying to be one) but from your posts and even your screen name, I can tell you are playing a lot of self destructive mind games.
First of all, drop the label "social phobic". By thinking of yourself that way, it makes it seem as if a phobia is real and tangible. It's not. Think of it this way- in certain situations and by thinking different thought, you experience fear. Not only that, but you probably fear your fear.
Now, if you could just think of those emotions as just that, emotions, you wouldn't be thinking of killing yourself. But you obviously aren't thinking that way- as I said, you are playing destructive mind games. To give an obvious example, you are playing the "It's not Fair for Me to Have These Problems" Game.
I know how you can be helped right now. Not necessarily about the social phobia, but about your depression. You should talk to me. Do you have an IM screen name or an email? And remember, your emotions are just emotions :wink:
