Urizen, hang in there. Yes we all get depressed by it but there is more to life, like good friends. It sounds like you have some friends that are going through it. They may seem "ok" with it, but I'm willing to bet its hurting them inside too. You guys can support one another.
Definitely throw yourself out there, join some athletic club(s) at school like martial arts or a book club. Most likely you'll find people there who will like you for your inner self and not so much the fratty kind (no offense to fraternity guys).
Like drmstx said, concentrate on school so you can make the big bucks to get a kick a$$ HT.
