Sibling Sexual Abuse Survivor

For a decade I've pretended that nothing ever happened. For years I've kept quiet and acted like nothing was wrong. When I got married, I even included him in my wedding photos and having him and his girlfriend at the hospital for the birth of my daughter. For years I gave other stupid excuses to mask the real mental anguish I was in. In my teenage years I began to believe I was dirty, that I was ruined, and that my life had no meaning. I wanted to tell someone. I wanted someone to erase my brain and take away my flashbacks... Little did I know, I wasnt the only victim here. Visiting my parents recently, I uncovered a dark secret. My little sister asked to talk to me about something important. I asked her what was wrong and she burst into tears. She started off to say that she couldn't hide it anymore and proceeded to tell me about her experience with my brother. I felt my heart shatter. How could I let this happen? We decided to tell my parents. I told them what happened to me from age 7 - 14. Then my sister told them what happened from age 4 - 8. At first it seemed like my parents were upset and they even shed a tear or two. shocking. Then my dad said 'Oh he was probably just too curious.' Its been a month since we told them. Nothing legal has happened. Just as I expected. When we were molested by a pastors son 6 years ago, they never did anything either. Right now, instead of helping her, they're invested into my brothers upcoming wedding. They text me all the time asking me if I'm going to the wedding or what dress am I putting on my daughter for the wedding. My brother banned me from his wedding anyways because his fiancé hates me so i dont even know why my parents are basically forcing me to go. This hurts me so much. Im sorry for the long post but I just need to know if anyone else has gone thru something like this and what you did to help your sanity.
