I'm being bullied I cry so much?

Ok so I just started ninth grade this year, and I found out that these mean girls in my cl before were in the same cl as me. I don't know what happened, 2 years ago they were my best friends. We used to talk all the time and have fun, until this new girl moved to our school. After about a week when she moved, my friends and her started making fun of me. They asked me to meet them at school to talk about some things, and they stood me up. They constantly bullied me, and I told the teacher a few times. The teacher talked with them, and they said I was bullying them which was not true. Our teacher made us apologize to each other, and they didn't ever bully me again until this new semester started. They spread rumors about me, and make fun of me and call me names. They push me and hate me. I don't know what I did to them. I have no friends at school, and the girls say that I'm the ugliest person ever, I have no right to be born. They threaten me and make racist comments towards me. One of the reasons why they bully me is because I had a serious accident when I was younger, and they make fun of me about it and I cry. They throw staples at me. People hate me because of all the rumors they spread. Even a guy I don't know tripped me and I fell. Then everyone laughed at me. I hate my life, I have no reason to live it. I eat my lunch in the stalls, and the girls follow me and talk about me while they're pretending to not know I'm listening to everything they're saying. I spend my recess in the bathroom. My dad doesn't help me since he's at work all the time. My mom is not here with me. I don't get why they just suddenly started ignoring me in 7th grade. They are a group of 4 girls. We were very good friends, for 6 years until the new girl came along. They've even made a new name for me; Leslie Pig face. They make fun of how I look, and call me les. I cry myself to sleep everyday. My dad works very hard for me, and we're having a hard time paying for the rent.
