I am sorry for the pain this family is going through. Is it possible to move mom away from this? I know that seems drastic. Robin will have to bottom out and take care of herself. Her mom is my mom's age and I know sometimes that age needs taking care of. Although my mom would fight it. I would have to be very persuasive and have a good selling point. I could see me moving mom into a very small place or with myself until this settled. I would be afraid one of the types Robin is running with would follow her and harm mom. Again prayers for all this family.
