Zen I wouldn't give her the time of day anymore either. I also have a sister who is somewhat like this. I refuse to speak to her, because she is a very controlling person, and talks crap about people behind their backs. Yes I love her, but there just comes a time in a person's life when you get fed up and say enough is enough! I also can't be around her because of my panic disorder. So Zen if she makes your anxiety worse than what it already is then I would say leave her alone.
