Hi Alone and Confused.
Welcome to the forum!
While your mom is not drinking, talk to her about AA. Gently. She may think she is well, and AA is not just about getting people well, but keeping them that way. If she is lonely, she can meet new friends there. Exposure to other people who are trying to lick the same problem could help her realize the course she needs to take. A mirror is a useful thing.
Of course... you can't make her go. You can only present it as an option. YOU have the option of finding an alanon group for yourself to help you cope with this.
Keep posting.
