Been harrassd at school...

Long story: This kid named Jacob asked me out, I said no because he has a horrible past with women. Well he thought I was joking and asked a few more I said no to everyone, well he didnt like it and started spreading rumours about Me, which I didnt care at the start. Until he made me and my friend Skye not be friends. He spread a rumour saying Skye said I sucked some dudes dick. So I found out Jacob said that not Skye. So everyday at school he calls me a slut, whore, bitch, cunt, idiot etc daily its horrible, I tell the teachers and they dont do anything. So this girl at school Literally attacked me, she pulled my hair, punched me, kicked me and abused me. So now everyone looks at me as weak and this kid Aidan is saying all these year 8s, 9s,10s are all gonna kill me and so many threats. So now the police are involved and Its serious I was starting to think suicide and I dont know what to do. I am so scared
