Help assualt

So yesterday at school this guy and named Connor (my friend jays friend) asked me what day it was and I said Friday and then he kicked me In the butt when I told connor not to touch me. I Connor constantly touches me and kicks me and I tell him not to . And when my BFF’s confronted Connor he lied and said he never kicked me I kicked him which was a lie and then I told some of my other friends and then they went to play basketball with him now my BFF is standing by me and now we are both trying to figure out a plan because I am scared to be alone and ya idk what to do this is giving me PTSD and making my anxiety and depression worse
