Please help me

This bully thinks he’s my friend, he has mood swings sometime he “likes” me and sometimes he hates me. He hates me right now and tomorrow he said he will physically abuse me all day in school. I can’t tell a teacher as I will be known as a snitch. He takes money of people and physically abuses them to impress others. He is a racist, homophobic, bigot, discriminative a-hole. It’s embarrassing because he is much bigger and stronger than me so I can’t do anything.I really don’t like him. He gets others to verbally abuse me and it’s very annoying and embarrassing. He’s racist to my dads race and religion. I have a black friend who he calls racial slurs and makes fun of many people. I don’t know what to do I really need help, please respond
