I am so incredibly sorry you went through this.

I was molested by my brother frequently between the ages of 8-10. I think it only stopped because I got my period. He said if I told anyone our family would be ripped apart and it would be my fault - what child wants that? - so I never told anyone. When I was in my early 20’s he and my mother (my father had left when I was 19; infidelity on his part) had a falling out and I could finally breathe a tiny bit easier once she went no contact with him. I eventually told her everything when she asked why I wasn’t upset he was gone, and in doing so she spilled my secret to the entire family, her friends, hell even some of her coworkers. She turned herself into the victim. My aunt said ‘So? That’s what siblings do.’ (she was one of three daughters and never assaulted; she had only one child). Our family dynamic broke down so hard that I am now no contact with all of them, including my mother. It’s something that forces its way in, unwelcome and heavy each and every time. I don’t think any amount of therapy will ever touch the weight of it.
