My mother is the "A" in my life. Been drinking for 65 yrs (lots & lots) and it continues today, I called her this morning at 10am and she said she was having a small drink! Right!
Believe me,it is a miracle that she is still alive. If I were a betting woman I would have bet that she would have been dead 20 years ago.
So, what I have realized is that I cannot project into the future, I cannot change her and that if I have strong bounderies in place and enforce them, I can be somewhat at peace.
She will die an alcoholic, that is reality, one that I must accept.
Work on you, accept what you cannot change.
