Please help

I just recently turned 13 and I’ve been molested by my theater teacher 4 times and was raped once. I don’t know what to do because I have no proof and he’s a seemingly nice guy who has worked there for years. I’m afraid to come forward and I’m even more scared that nobody will believe me. I’ve only told one of my close friends and he’s been pushing me to tell the (racist) vice principal about it. I don’t know what to do and I’m just scared. My friend is buying me pepper spray and is being super supportive, and I know I should come forward to protect other girls like me but I’m scared. I have to go to this class every day and pretend nothing is wrong and I don’t know if I can make it much longer. I had a failed suicide attempt last week and now my parents are super concerned about me. I’m just too afraid to tell my parents because I’m afraid they won’t believe me. What should I do?
