I was raped by a woman

I was raped in highschool by a woman in her 30s, she was the mother of one of my friends who thought I was gay, and I never came out to her because she seemed homophobic. I had just turned 16 and this woman had lured me to her apartment, it was my first time drunk. She got me drunker and druggier until I could no longer remember what day it was or where I was, the only reason I remember it so clearly is that she was so enthusiastic about me being gay. She was very vocal about how much she hated gay people and wanted to know my "first time" story. I told her how I got head by another guy and his older brother, but I never came out to her, and she made me feel guilty for lying by saying that I'm disgusting and should be ashamed for being gay. She said it as if she was trying to make me feel bad for not being gay enough. I didn't want her to think less of me because of how gay I was, so I let her take advantage of me. I didn't remember much after that, until I woke up in a random park. I was told that she was a sex offender and that she had been in and out of jail for various crimes. I went home and never said anything about it because my parents would have called the cops. I felt like a piece of shit for not coming out to her and that I was responsible. I didn't come out for another 2 years. I feel so ashamed that I let her do that to me because I should have just come out to her, but I was scared. I didn't want to lose my friends because of how gay I was. I didn't come out because I was gay enough for her and I felt like I was worthless, I had to let her rape me. I just feel so ashamed. I'm sorry if this is confusing, English is not my first language.
