My sister has gotten Brazilian waxes for years, and now the hair is permanently gone. Recently, she has become so obsessed with regret over this that she had panic attacks for days, and her doctor tried to hospitalize her. Her obsessive talk about the topic of her waxing was more than I could handle, and I had to tell her that I couldn't talk to her about it as often. She got mad and accused me of being unsupportive, and she said that if I was going to limit how much she could talk about the problem, then she was going to limit how much we could talk about any of my problems.

The other day, my sister was being really supportive and loving toward me as I talked to her about my real estate woes. I'm not obsessed with my home search, it's just a run-of-the-mill problem that I have. All of the sudden, she said "You've talked about this before. I don't want to talk about it." She said she was cutting me off because I had placed a limit on how much she could talk to me about her pubes. This was all over text. I didn't even say anything, and she launched into an attack on me about what a bad person I am, how I can't be trusted, how she doesn't like me and never did, and how I have borderline personality disorder. 

What in the world...?
