He raped me I'm only 14 what should I do?

I was raped. August of last year. I finally told my mom because I couldn't take it anymore I couldn't keep it to myself. That man took away more then just my virginty my mom wants me to report it but I don't want to nbecause I can't relive it and tell the whole story I also don't want to deal with it because only 10% of people accused are actually arrested. I also don't have much to tell the police because I honestly can't remember much so they wouldn't have much evidence to look for him. And if they don't have any leads within 30 days the case gets put to a rest.  That isn't right. Is it worth all of that? I don't feel like it is. But I also know if I report it I could potentially save other girls. Idk what to do I just want to act like it didn't happen and move on.
