My mother has early Alzheimer's too. It's making her increasingly bitter about how her life has turned out, with me, her only daughter not attending the meetings, becoming unexpectedly a widow, and the biggy- the end still hasn't come.
She wants me to come out and visit her, but she says mean hurtful things, like "You need to have your head examined", "I don't know what's the matter with you, Virgochik, maybe I dropped you on your head when you were a baby" and plenty more zingers. It's so hard to even call her because she always works in comments about the meetings and demeans my character for not going, when basically I'm a pretty good person, I think. She lets me know how wonderfully the sisters help her out and makes digs at me, though I live about twelve hundred miles away and trips out to see her are expensive.
My heart goes out to all of you and wish you peace of mind. It's so hard knowing how much of their malice towards us is the disease, or their true feelings egged on by the cult. My mom could go at any time, and I may carry that gnawing question forever without an answer.
Sure wish I could blame it on the ALZ, but I've read up on it, and it basically takes the person's personality flaws and magnifies them. If she was always a sour negative person, she may be even more so.
This thread is so comforting and informative. Thanks to everyone who shares their journey.
