What is the dynamic you are in? People play terrible group dynamic games. and one of the things they do is gang up. If you look around at teh whole dynamic it might show you why you are being picked on.

If you put a whole lot of piglets in a pen with nothing to do they will eventually kill the littlest. And then they'll kill the next littlest. And then they'll kill the next littlest... If you give them toys they won't kill anybody. This is what I mean when I talk about group dynamics. Somehow you're the littlest pig, and they're bored.

So look around at the ones that don't get picked on and ask yourself what smell or look they give off that means they're not picked on. And learn it. :)
