I haven't been raped but I've been close and I know how disgusting you feel. I know how you imagine that it's your fault that you could have done something different that you're afraid that people will call you a dirty little slut that was asking for it. That you shouldn't have been alone that night but the fact of the matter is it's not your fault. It's the person who did that to you. They're the sick one. They're disgusting and you can go to the police and not tell you parents if you want to it's your choice but I think you should talk to someone about it. It'll help you get past what they did to you. If you go to the police they can catch the bastard and you won't have to be afraid that it'll happen again or that it'll happen to someone else.
