What do I do about my crazy mother who keeps trying to make herself a part of my life?

My mother is exactly the same. The best thing to do is to ignore her and tell her to "F*ck off" if she crosses a line. She won't see it coming. My mother plays the victim as well. Just don't feel into it. The less you react to her actions and the less you speak to her the less she'll want to tell you about her drama.
