First crazy party

So last night I went to my first high school party and it was really crazy. I know this is really stupid but I ate a brownie with weed in it and took multiple shots of vodka. I am not used to lots of drugs or alcohol and I got really fucked up. Anyway the police showed up and this fuckboy who is three years older then me pulled me into a bathroom and all I remember is him putting his arms around me and then I can't remember if anything else happened because I was super drunk and high. This boy and I have been hanging out a little bit but I know his main motivation was to have sex with me. I'm really scared that he did something to me in the bathroom that I can't remember. If anyone could please give me advice about what to do I would really appreciate it!
