I'm trying to deal with a mother who is a closet alcoholic and cruel. She knows what is closest to my heart (my children) and what will hurt me the most (attacking my parenting of them). Her most recent attack focused on this, and I am still reeling. I have a history of anxiety and depression -- she is aware of this -- and I take two medications to manage these conditions. Her behavior exacerbates these conditions. This has been going on for approximately two decades. My husband and I are considering leaving and severely reducing or ending our contact with her. Advice?
