I have been raped and I have lost all hope

When I was 15 I lost my virginity and became super lonely and abused it. I started having sex with older men and started seeing this one particular one after school.

He was fairly young and told me he loved me and I was his girlfriend. He raped me. I feel like I couldn't leave because I didn't wanna be alone and I had nobody so I let him keep doing it

I also started seeing other men to cope, who introduced me to drugs, drinking, etc. It became almost an everyday occurrence. At one point I had to piss in my own vomit and eat it to satisfy a guy.

I had tried to change schools and have a new start. My parents deemed my unusual behavior as just a phase and told me just to make friends. I felt like I failed ultimately and had nobody on my side.

Currently I'm 16 and a sophomore. I'm trying to find any possible way to graduate early and leave this place. I have thought about just dropping out completely and getting a GED. I still drink, smoke, etc and I am so lost.
