Rape?

On Friday I kinda accidentally roofied myself. Took Xanax and then was drinking. Didn't realize what I was doing as I had just taken a sedative... my best friend asked me to come over to his house. It was 2am. He knew I was drunk and picked me up. We got to his apartment with his roommates sleeping in the bed across from his and we were cuddling. He started taking my shorts and panties off and I said no but eventually I agreed because he said it was ok and that he wasn't going to do anything. He tried to have sex with me and I said no but again eventually agreed. I've been beyond suicidal recently because he knew about my past of sexual abuse from my father and I feel used but I don't know what to call what happened to me because I had been drinking and I agreed..
