two solutions, one violence. It will have consequence as then the school will come for your ass.
Two, the police.You are currently being the victim of a crime. What they are doing is illegal and a visit to the police station may calm them down. The thing is, they don't only target you because you are both weird and better than them. They are targeting you because they feel like you are weak and they will face no consequence. The best idea to get rid of them is to bring down consequences on them. Report them to everyone, inside and outside school, be vocal about what you are living through
