I been bullied by classmates today, What should I do?

It's a few people who told me: I am hairy (" You have hairy arms"), the class "bitc.h" told me I look like this "woman" who is a transvestite http://hannablondk.blogg.se/images/2011/vanessa-lopez_138970510.jpg (this is me :http://img199.imageshack.us/i/18045218190320850141516.jpg/ ) , someone of them even threw gum in my hair so we had to cut some of it off.. And the person did it on purpose I've heard(he said he tried going for my "hair legs" even if I do shave them.... I'm really hurt...It hurts so much inside me.. Don't call me Emo please.. I don't have self-esteem at all.. What should I do?
