Can't take it anymore

So this happened a few years back when I was about 19/20 years old when my step brother sexually abused me. He used to touch me inappropriately but when it started, I was confused. Wasn't sure what was happening. Oke day during my step sisters wedding, we all were tired and were sleeping, i was sleeping right beside him, facing him when he turned me around and held me tight. I started to feel uncomfortable and after a while I felt something poking me. That's when I got up and ran away from there. After coming back home, I told this to my mom but she refused to accept it and we had a fight. She thought I was overthinking and so I started feeling the same.

After a few years, I found some of my private pictures which he took and that's when I was sure that it wasn't all in my head and I was right all this time. When I showed those pictures to my mom, she stood with me and supported me. But that wasn't the case with my dad. He accused me of leading him on and blamed my clothes for whatever happened. My mom even took me to file a complaint against them but because my proofs weren't enough as the pictures didn't had a clear view of my face, or advocate adviced us to not file a complaint as the case wasn't that strong and we weren't financially independent. My mom and dad were on the edge of getting divorced, i had become suicidal when my mom took a decision to get away from him and the city. We shifted somewhere else but after a few days, we had to come back because I was yet to complete my exams.

When we came back, my dad thought everything was normal and he made sure we kept quiet. My mom made sure my education was completed. Today I work in a well reputed company but I am still tied to him. My dad wants me to get married to some guy he chooses. Lately I have been feeling disgusted by the guys that he wants me to meet. I had no idea why this was happening but recently something triggered and I figured it out. It's because the guys are selected by him and his son. I feel disgusted talking to these guys. I feel like shouting, screaming and asking them to stop.

I want to cut all the ties with him and his son which I am not able to do. Now that I have started understanding things and I am financially independent, he (my dad) has stopped fighting or forcing me into things (which he used to do as I grew up) now he emotionally blackmails me into doing things against my will. And I am not able to fight back anymore. I have started getting panic attacks again. I don't feel like doing anything or even talking to him.

I want my younger self to get justice but I feel helpless. I want it all to stop.
