Trying to find who I truly am

I feel that I have never been able to be who I truly am. I was abused by my uncle from I think around 6 until 18. We lived with them and the reason I don't know the age I was when it started is that I remember nothing in my life prior to it. I know the exact story of the first time it happened and it then happened so frequently that I couldn't count. Many times a day, many days a week, many weeks a year etc. It has ruined who I am and my personality now is one of full compliance. I can't say no to people, i let people abuse me in many ways, not just sexually because I do what I have to to please those around me. I told no one of the abuse until 18, and have only told my husband. I have now found out that another cousin suffered the same and her life is absolutely off the rails. I think it happened to all of us, there are five girls but we simply never speak of it. He is still alive, I don't see him, none of us do as he is a drug addict. I want to seek justice but don't know if I am strong enough to survive that. He made my life a nightmare, he changed who I was, he destroyed me.
