Reporting a Rape/Drinking Underage

So back in late October I was raped and sexually assaulted on two separate occasions, one of which I was drinking underaged. I don’t know their full names I don’t have their numbers so I can’t find out, I don’t really know what to do. I don’t want my parents getting involved with this shit either. I’m 18, so would I be able to handle this alone? And what should I do about reporting it? And what about the fact that I was drinking underaged? I just don’t know what I should do? Please help
