Hello and Welcome, Amerce72.
I have to say that for a while I severed my parents. I was younger. In a strange way, my current life has allowed me to open my eyes to things that happened in my past. Because of current issues with my AW, I've been able to more openly discuss these issues with alcoholic parents and I believe we've all found a way to forgive each other for our mistakes and I'm much closer than I ever would have imagined.
I've been in your shoes so I know how it feels. I may be one of the luckier ones.
