Never ending

Since primary I have been bullied so when I moved up to high school I was excited it was a new start. One boy who I won’t name for his privacy decided off the bat he would make my life hell. He disrupts the class every day and everyone loves him so he just hits and pokes and pushes me he humiliates me infringing of the whole class and even my best friend is friends with him. I have told the teacher too many times and it only gets worse ingnoring him doesn’t work a now I’m in s2 and he has got way worse. Everyday he tells me and the whole class how he’s going to kill me, acid, fire and so much more he sexually harasses me and more I don’t know what to do and it still hasn’t stoped and I fear it never will.
