SERENITY NOW!! 😡

I am two steps away from strangling my mother in law with my bare hands!!!! I refuse to bow down to her manipulative narcissism any longer. I'm done. In the words of one of my students, "I'm bout ta put dem paws on huh!" How do you deal with someone who constantly judges everybody, claims that everybody is out to get her, thinks everything she does is perfect, makes every situation about her, and plays the victim no matter what she has done wrong (of which she never acknowledges)?
