I think it also drives them nuts that the attention is not on them.
I totally agree with this!
My BPDm would rant, rave and generally call EVERYONE an idiot. They can't handle that there are not the center of attention, getting sympathy and support.
Yeah, she accused me of not being supportive last night. (I answered my phone at 11pm and offered to change her plane ticket. I'm not calling her every hour and hand-holding, if that's what she's looking for). I think she's punishing me for going out of town with my healthy friends for the holiday. Too bad.

She can't deal with losing people, which I understand. She tries to railroad people into managing the situation the way that makes her most emotionally comfortable, which is terrifying when the situation is about someone who is in physical distress and rightfully should be the one in control. She projects her anger onto the sickest person, or their caregiver most often. It is one of her traits that I hold in total contempt, even more than the arguing or hoarding.
Ironically, she considers herself to be a nursing professional.
I also think that she is terrified of death because she is living a weak, unfulfilling life. She sits around moping and ruminating, and doesn't partake in the joys of this planet, and has a major existential crisis when people need to die. She left me to deal with a pretty intense long distance hospice situation in my late 20's because she was being a jerk and couldn't face the family.
