When I went to school I was shy and extremely submissive, I was constantly kicked and punched, and a lot of guys kept talking shit about me. My friends where kind in the same situation, so no one ever said nothing and we all just ignored the bullies.
But one day, after playing rugby for a few months I realised that I wasn't made of glass, and that when I got angry I could make a 130 kg go down to the ground (i only weight 78 kg). So one day one of the bullies kicked me in the butt, and i just went berzerk. I lost control of the situation and ended up bashing this little fellas head against a tree. Violence aint the solution to nothing, (I felt so bad for hurting that guy that I actually started crying xD) but this is a sick, sad, little world, and sometimes you just need to let go the beast within.
Big hug to you mate, hope this fucking situation gets better for you, and remember to find support in your friends and family (and of course the nice pony lovers from this forum!)
(BTW, Rugby also helped me become stronger and gave me some of my best friends, you cant imagine how fun it is to go party with 30 guys that weight nearly 100 kg (or more), dont know why but there are no fights when they are around )
