Trigger Warning* Sexual Assault

I am currently in college and I was raped my second day on campus and was a virgin before the rape occurred. I'm close with my parents and am going home with them soon to visit. I haven't told them yet but I want to. I don't know how to tell them at all. Ive told some friends and my school knows about it and I already went through medical tests and I didn't contract anything from him and I am not pregnant. But I don't know how I'm going to tell my parents because I don't want them to pull me out of school. Any and all suggestions are welcome. Thank you.
