IM 12, A GIRL AND GETTING BULLIED :''''''(?

Ok so my "best friend" is emotionally blackmailing me about the dead but thats not whats upsetting me. its other people talking bad stuff about me. ok so let me describe myself before i tell u the story: i have brown hair blue eyes and i dont look as common as most other year 7s in my year. Im very shy but would never dream of hurting anyone and if the boys say bad stuff to my face i insult them back but not as harsh. k so theres this one guy ( I KN0W, GUYS SHOULDNT BE BULLYING A GIRL) but he is and he says stuff like ur moms a prostitute! and i have to go to student support and miss a lesson each week for it its confidence boost and when an SSC teacher gave me a letter he kept saying i go to SPACCA SUPPORT CENTER! and he kept saying it all lesson to me! kk so then this other guy calls me alien sometimes to my face but mostly behind my back because my forhead is quite big! and this girl she put on private chat to me on facebook, ur reali pretty, then she put JOKES! and i burst into tears u know. being a girl and being misunderstood and called ugly is the most hurtful thing when u know deep down inside ur beautiful in every single way and nothing is wrong with u it makes u want to scream the truth, but ur voice is left unheard. people just keep saying stuff to me like reTARD and they spread rumours and its killing me. id raver be physically bullied because i know how to fight and i would fight back but i cant speak back. i do have a group of friends but its no use when other people keep knocking ur confidence when u even take a class to build it. when im at home im happy and in my own little world with just me an my family and not many cares but now they are even wrecking that for me! how do i overcome this i told my tutor and he said he would have a word with their tutors but he hasnt now! and i cried to the student support an he told me to tell my tutor which i did but no change! Secondary school has dashed my hopes and dreams before they even begun.
