I too experienced incest as well as other CSA. I have found this site enormously helpful and have found a generous therapist who has helped me work on this pain and confusion. You would think I would have some amzing insights here but the truth is I don't. I only know it is not our fault and it scarred me like all the others. It is a bigger violation and hurt when it is familial and you are confused and trapped in shame and secrecy. But it is not your fault.
Talking , journaling and praying helped me but tears and going through the range of emotions help. My dad was dying when I confronted him and could not respond, while my brother denies it. I am in a place of actually forgiving them now.
Don't compare me to your story because we are two different people. This is the hardest work I have ever done but it is worth doing. I hope this helps. PM me any time and I will do my best at responding. You are in the best place I know of. You will be heard and respected.
When you stumble, make it part of the dance.
