13 and got raped.. What do I do????!!!!?

kso, first of all i am 13. I got raped a few days after my birthday wich was like a week ago. Im not going to tell you the whole story about how i got raped because thats a long story. All i can say is that it was a man that i did not know and hes was probbaly 30 or 40. Anyways I think i developed an eating disorder a few days after. I dont really know. But for a while i litterly just stopped eating. Then I just pigged out on junk food then felt guilty after and made myself throw up. And i just wanna say that i am fat. I know i am. I have been called fat in the past and it hurt alot. Also I started cutting my wrist a few days ago I sware to god it makes me feel alot better. A few weeks after I got raped I told my vice pricable. She called me a councler and I had to talk to her.Then they called in the police and I had to talk to him. It was honestly the hardest day of my life. I wish I never told her. I felt like killing my self after I talked to all those people. She told me that it was her job to let my mom know about everything. So she called my mom and then let her know. My mom came home crying and stuff. But afterwards my mom seemed to be making this more about her. She started telling all of her friends she was really sad. Then she would tell them what happend to me. She even told one of her friends that I never even met. I also warned my vice princable that my mom would end up telling people! Im not really close with my mom though. She calls me a bit** on a daily bassis. And she slapped me across the face when i was like six. And last year she slapped me across the face for taking my labtop to a friends. My mom has also called me fat in the past. I have also lost close to ten pounds. I was 130pounds at first now I weigh 123pounds. and im proud about that. I like feeling skinnier!!! Also I hate my mom because when she had a boyfriend he would be a jerk to me no joke. and i would cry myself to sleep when they were dating. I didnt deservve that. My mom and dad also devorced a year ago and its really hard. I just wannna end my life!?:( I sware to god its the hardest point and im just ready to let go.
