Well after many recommendations I went to alaon today! Well done me, even if I do say so myself.
It was very comforting to hear and tell similar stories about how drunk family members affect the people around them. I'm not bonkers! Hurrah!
I know what I have experienced is just the tip of the iceburg and I still don't have a clue how to detach with love, or how I have my mother actively in my life but I think I may uncover this with time.
Thank you to those who suggested I go, I can see how this may benefit me in the future. I will keep you posted
