I think I was drugged and raped by a guy I had sex with 3 years ago and I just realised now. Is there anything I can do?

I remember at university I went to his house with a friend and they were 2 brothers. We were meant to have pre drinks and then head out but it became too late. I think she willingly had sex with the other brother but I don’t think I was willing. I was really angry in the morning when I was leaving and I wanted to smash his TV but I had no clear recollection of why I was angry that we had sex. And even when I saw him weeks after, I remember being really upset again and angry. I think deep down I knew something wasn’t right about what happened. I was never really someone to have sex on first date either, I usually would stop sex on a first meeting guaranteed, even if I was drunk. Ever since that day whenever I saw him out and about in clubs I was angry but no clear memory. One time his brother approached me in a club and I shouted at him to fuck off.
Today I was just looking at my past trying to forgive things that happened in the past, I started thinking about him, I was confused again as to why I hated disliked him so much, so as I’m searching my memory I realised I don’t remember too much of that evening after I drank but also don’t think I drank too much. After I drank I remember he was really direct in a way most guys haven’t been he was groping and pulling my skirt up like no testing how comfortable I am. I don’t remember how I got upstairs, now I think I remember saying stop stop several times but my memory is hazy. I don’t remember what the room looked like, like nothing and that’s not like me. I just remember him having sex with me. I don’t even remember his facial expressions much so I’m recalling even having my eyes closed, half sleeping and I think that’s why I was so angry because maybe I was trying to control but I couldn’t because most likely I was drugged? Back then I didn’t know much about drug rape so I think that’s why it didn’t cross my mind. I’ve been to other guys houses when I’ve been drunk and I recall! A lot more detail than that day.
