Is there a daytime meeting you could get to during your lunch break?
Glad you found a new therapist, the old one sounds awful, not to mention terribly ignorant about alcoholism. If anyone here could save another person from alcoholism this site wouldn't exist.
I do remember you posting about your mom on another thread. She sounds very melodramatic and it seems like it must be exhausting trying to keep someone like that from having meltdowns. Just try to remember that her responses to adversity are her choice. It is not the fault of you or anyone else if your mom chooses to take something personally that really isn't her business.
