well, first of all, im a girl and im in middle school. im really skinny and kind of short. theres this fat girl in my class shes taller and waaaaaayy fatter than me, and we dont get along because i have a nose piercing and she doesnt. she has been trying to piss me off ever since she got to my class, because she used to be in another class, but she got switched to mines. she always calls me an indian (because i have a nose piercing like if one has to do with the other). this one time we started arguing because she was talking about me. and now the last time when we started arguing was wen we got to the point where everybody was yelling fight!! fight!! and people were holding both of us so we didnt hit each other, we started cursing at each other, then this girl came to me and said that the girl wanted to tell me something and to go to where she was. i told her that if she wants to tell me something she had to come to me, so she did. she started saying that she doesnt like me, and she swears to god she would rather die before she did, and then she started saying that im a ***** and she said she would smack me, then i told her to come smack me, and she did, so then i smackecd her back but i hit my back in the classroom board, and everybody was holding me so that i didnt hit her because then i was gonna get in big treuble (with the principal, i could get suspended...) so then i started crying because i was mad. now every single day i go to school every single person exept my best friends keep on making fun of me cause of it, even 8th grade people that ive never even talked to. everybody is talking about it, i cant stand it anymore!! what do i do so that people stop making fun of me?? by the way when i hit my back on the board my back still hurts a lot. its actually my bone.
