Hi Somegirl and welcome. Don't feel badly, posts sometimes don't get responses in order of the queue.
What happened to you is terrible. The fact that it happened over a long period of time and that it was at the hand of a family member that you should have been able to trust must make it very painful. When a child is harmed repeatedly within what should have been a safe place it is very traumatic.
I am sorry that you had to endure such abuse. I am also sorry that you are struggling with alcohol. I am very glad you are here. You were an innocent victim, and I am wondering where the caretakers were in all of this. It is courageous that you are speaking up, it is never too late to understand our past. Sadly, you can't erase it, but with the right help, you can make sure you are not robbed of any more of the life you deserve.
Not sure how much you know about alcohol abuse, alcoholism, and do you have a therapist, or any sort of face to face support?
