I hate my school so much that I want to drop out?

I hate my school, I want to change schools because I'm not happy there at all because I get bullied alot and if I tell an adult at school I might get jumped by some of the kids. I hate school, I'm been so depressed my whole time there and I feel so alone because everyone in the school made up rumors about me and they had said that I sleep with the whole football team. I haven't made a single friend at all while I was here. It's almost the end of my Junoir year and I want to give up. My grades declined severly, because I couldn't concentrate on school and I had so much drama in my life lately. My dad isn't letting me transfer to another school because he wants me to graduate from this school. I told him if I go here during my senoir year I will skip everyday and I will dropout. Why won't he let me go to another school nearby?
