Where are you located? I can relate to how you feel. I was like that for few years until I finally find few close friends (not long ago).. Sometimes, I even think finding a good friends depend on luck.. Are you freshman at your university? When I was in my first year, I was very lonely as well. Anyways, add me on gtalk.
There is a small chance you attend the same university I do. If you do, message me (FB, twitter, email... I don't care). I'd be happy to grab a coffee or something.
