sorry for the novel in advance

So it was my birthday drinks and the night was going well and everyone was behaving and getting absolutely munted, everyone started to toddle off to bed and I was outside throwing up because it was my birthday and I was absolutely smashed and a guy came out and pulled all my hair back and I was like “okay cool he’s gonna help a sista out” then I finished throwing up and he pulled me up by hair and pushed me against the wall and kissed me and I was going through a bad break up at the time and being smashed I was like cool someone’s into it and surely my friends wouldn’t bring someone into my home that’s dangerous so we carried on inside and he was being a bit rough but I didn’t think much of it then it got really rough and he started hitting me in the face calling me a stupid bitch, then he held my arms down and got really rough. Then he hit me in the face again really really hard. Then he pushed himself into my ass with no warning or prep work anyway and that was when I started really crying, then he pulled out and grabbed my hair and forced himself into my mouth and throat and I couldn’t breathe then he pushed me back down and started having sex again then he started chocking me crushing my windpipe and he whispered in my ear that he was going to fuck me till I was dead then I blacked out and the next thing I remembered was waking up struggling to breathe and my best friend was sitting next to the bed stroking my head trying to reassure me that I was fine and then I was just in and out of consciousness for a couple of hours but I don’t know what it’s classed as because I never said stop or no and we we had both been drinking. I just need to get it sorted in my head because it’s really messing me up.
