Point her to a meetings list, and that is all you can do.
I wish my husband would go to Al-Anon. Besides the fact that he lived with my drinking for years, he is also an ACA like me--but is in denial that his dad ever had a drinking problem, despite the fact that he had to go fetch his dad at the bar on a regular basis from the age of about 8. But so far, he won't go to Al-Anon. Doesn't like groups, already sees a therapist, dad was not really alcoholic, blah blah blah...
Yes, I am disappointed about this. But, my disappointment does not help at all. In fact, it harms me AND him. So, I try not to focus on it.
Bugging him about it does NOT help. (I know from experience!)
Him seeing me working my program MAY help. I've just recently embarked on it, so patience and time may help as well.
The same would be true for your mom. She needs to work her own program if she truly wants to. There is no way that one person can work a program for somebody else. There is a difference between pointing the way, and doing it for her. One is possible... the other isn't.
Luck! xox
