I had a problem at school today?

so in my chemistry cl last period we did this lab. and my friend was in there well i cant really call him my friend becuzz he talks about me behind my back and he uses me. today he asks me for a piece of gum and i said NO go eeff yourself and get outta my face. so then he said i was white trash and that i was a wigger im not a wigger i dont type like one and i dont act like one and he thinks im from the projects which im not i live near it but he always asks me if im on drugs which is really eeff'd up and it really made me mad that he called me white trash and a wigger so i picked up a jar of chemical reactions and i tried throwing it at him but it missed him and it hit the wall and broke but all my luck my lab partner was like that wasnt a chemical it was distilled water which wouldnt burn you soo the teacher kicked me out but i was soooo aggravated and angry and as i was walking out i told him i hopes he dies a painful death tonight and that hes lucky i dunno what car he drives am i gonna get suspended or expelled???? i really hope not i didnt go to the dean of students becuzz i wanted to leave school there was only 5 mins left in the period soo i ran out as soon as the bell rang. im so mad i missed him ggrrrr. but im serious he is really racist and i absolutly hate him with a pion i should beat the crap ouut him i dunno why i didnt though becuzz i could easily take him.
