Should I skip school?

My school is bullshit. I'm in huge trouble for retaliating against a guy who was saying rude things to me and about me. His parents came in and showed the messages I sent to him regarding to the stuff he's said about me. Everyone, including my parents, is pissed at me. Even my teacher said she was embarred to even have to know me. I already got switched out of his cl, but I want to skip school. People say I sound like my mother on the phone so should I call in? Also, I have to have an escort for the rest of the school year. I was supposed to be off, but the guy's mom emailed the dean and told her about what I've done to her son. He and his friends have been giving me a hard time since last year. I've tried to tell my teachers, but they said it "all in my mind". My imagination. I'm just thinking he's saying those things. Also the boy's mom is making up stuff and taking my words out of context. She said I threatened to boil and cut up his dog. All I said was "It's not like I cut up your dog and boiled him and ate him, so there's really no reason for you to hate me." She's a lunatic and making up stuff about me! I've been bullied and he's getting away with it. His parents have money and are looking like good guys while I'm taking all the heat.
