Is my mom for real or completely self un-aware?

She refused to let my sister and I talk while we were growing up (later part; before that we were very close), and now that she got her wish (that sis and I arent close anymore) she is crying on the phone because she's dying and wishes us to be close again. She's the one that drove us apart in the first place. I cant say for sure, but I always gingot the gut sense of underlying jealousy when sis and I paid attention to each other instead of her. Selfish, and bad parenting, I know. But re. this crying, oblivious that shes the one who caused it herself... now is she for real? WTH to do???
