You can look on the site and look at the symptoms and decide for yourself.
They have great lessons and tools for comunication.
They have a board to talk to others in this situation, but it's pretty bleak.
My guess is that she has Borderline Personality Disorder. I don't have a degree to diagnose but I have a degree in Hard Knocks from the last two yrs with my mil. So far she has alienated all 3 of her kids, most of her siblings won't even talk to her. We still hear of her lies to anyone that will listen to her. When we first started, we had no clue. I kept searching just like you to find an answer. This fit her to a T. I will never let anyone else go without an answer. By the way, ANYTHING they do to you they feel justified. That makes them dangerous. Most people end up with LC or NC, low contact or no contact. There is little hope for a cure. Never tell her that she has this. I am sorry you are going through this. It has been devastating for my H's family. But knowing what it is has been so helpful.
Good Luck.
