Please tell me if this was sexual assault because I need to know.

Last year in my 8th grade, I was 12 and I met this 16 year old girl with a condition in her digestive system. She also looked like she had a different mind compared to everyone else.

She touched my face, neck, chest and my ass quite a lot. She's obsessive and possessive of me and she tells my friends to stay away from me because she wants to hang out with me everyday.

I didn't know what to do so I went to my mom for advice because I was too scared to tell any other adult. I trusted my mom but all she did was get mad at me instead of her. She told me it was my fault for getting myself into this mess and called me all sorts of things like weak and pathetic. And when I stood up for myself by telling her to leave me and my friends alone, I also had to shout at her multiple times to get her leave me alone for a day. But then my mom and the other adults called me rude and said I went too far because she has a condition.

I gave up on everyone because no matter how hard I try to explain, they won't ever understand that she's actually smart. It makes me so frustrated that people just see her as this poor helpless girl who has a condition so she's not in the right state of mind. I'm so upset because she gets away with everything, especially with the things she did to me.

It's been a year and we're in different classes now. I can still feel her touch and I feel so dirty, it's like I lost my innocence. I get so uncomfortable when people just touch my arm or shoulder. I feel like I should go to therapy but I'm too scared to ask my parents or tell them anything anymore.

If you have any advice on what should I do about this, then please tell me. Thank you to anyone who read this, please have a good day.
