For the small chance that this is not a troll post and you're serious about it:
Committing suicide is the most stupid thing you could ever do. Even if your life is shit, you're a young guy and you have all the time to change it. If everyone you know just thinks of you as the anti social loser maybe it's because you act like one. Just change that and people will react differently to you. And if that doesn't help you can always move to another city where no one knows you and you can have a fresh start over.
Making friends really isn't that difficult, just go to places where you can't avoid contact to other people, like sport clubs, and don't be a total douche. There will be at least one person who's interested in getting to know more about you. It's really not that hard...
