I'll admit..I'm a loser and a geek
You're 14, you have your life ahead, not behind you. Nobody's a looser with 14 unless you talk yourself into that. Then it becomes a self-fulfilling prophecy. So stop that.
That being said, I'm a huge outcast at school. I had a few friends but even those are starting to desert me. I'm made fun of and ridiculed constantly for such things as reading rather than talking during class when work is done.
For most people time at school is terrible. Being caught somewhere between dreams, nightmares and insecurity. I don't know anyone who hasn't been bullied by someone during his time in school. The bullies I know from my school usually had troubles at home and vented their anger at people who were weaker at that time. Preferably on those who just let it happen.
I disagree with people here who say you should resort to violence, because you probably loose there unless you work out a lot. Trying to beat a bully on his own terms is very difficult. But you should defend yourself, then they probably look for an 'easier target'. But don't get after anyone with a bat, sharp object or any other weapon. This leads more likely to escalation than to a solution for your problem. When the bullies suddenly surround you with bats of their own it's getting nasty.
Do you do any sports? I would start some martial arts if I were in your position. Not for beating the crap out of people (well, maybe to a certain part ;-)) but to learn to know yourself better. I started Tae Kwon Do when I was 13, which helped me getting more aware of myself, self-confident and learn how to handle myself in a fight if I really, really have no other option.
Beside this you should see if there is some team-sport you might like. Playing in a sports team helps getting social with people, since you have at least some common interest. But don't force yourself in some sport you don't feel comfortable with!
For venting stress and frustration playing some drums also works very good, or in my case bass guitar.
But don't start some crazy stuff just to please someone. It's better to be hated for what you are than loved for what you aren't. Sounds harsh, but you shouldn't try to be someone you are not. This might help short term, but makes you unhappy in the long run.
