My older sister sexually abused me when we were children.
She was 7 anx I was 4. It ended when she was12 and I was 9. It was consisted of her touching me and having touch me inappropriately and giving me oral sex, also gave her oral sex and had to rubbed her vagina.
I told her to stop but didn’t listen. I learned she was abused by a teenage neighbour. She told me not to tell anyone, not even our mom. I wanted to tell but couldn’t because fearing that no one seems to care. She passed away and never got justice. What should I do?
