She sounds so much like my mother. I didn't talk to her for a few years, and now pretty much just on holidays. Mine is toxic and always twists things. My sisters see the situation and I've got them to support me. I've also decided that I will let her into my life on the surface...Christmas, Thanksgiving...even my grown daughters don't much like her. I've poisoned them is her version...

I'm taking care of me first. I live a mile from her but don't have a car. So running over there to help her is out. I am also looking to move to a less costly place in February, so that will help too.

I don't hate her, but MY mental health is TOP priority! Best of luck to you. It's not easy to set boundaries when they are making things tough, but it is doable.
