I was raped and assaulted by 5 guys from my school, need a friend to help me get through this.

im 16, i got invited to this guy's party whom i thought was my friend. it happened a few days ago. god this is hard to talk about. skip the details ill just say i drank something, passed out. woke up feeling pain everywhere in my body stuck in a room with 5 guys. one of them was someone i thought was my friend. it was awful. their laughter and words are haunting my fucking nightmares. i can't even look at them in school, i feel like a piece of shit. no matter how much i describe how i feel it wont help. they took pictures. they said if i tell someone im already dead. which i believe because they aren't afraid to kill me and i know it. im trying to pretend it didnt happen but i can't. im barely functioning. i dont know what to do anymore. i dont know how im supposed to move on from this. i hate myself. i feel worthless. i just want to forget that night ever happened. i feel awful, it felt like it was happening for so long. i felt like i was gonna die. which i currently wish was the case. i can't tell anyone i know. i just want someone that can be there for me with this. i can't do it by myself. i feel like im gonna die. and i have to talk to the nurse about my bruises on monday which im fucking panicking about.
