Help! My mom has always been mean, nasty & narcissistic her whole life, but now, at 91, she's over the top. She is saying horrible things about my dad who passed away 3 years ago, and insinuating that he 'did' something to her to make her hate him for their entire 68 year marriage. She's chomping at the bit to tell me some horrid little secret, and it's only a matter of time before she blurts it out 'by accident'. It's gotten to the point where I can't stand calling her or going over to the ALF where she lives. She's threatening to jump out windows and saying she wants to die, etc, almost continuously now. Does this go along with dementia, or this something entirely different? Do you have a mom like mine and care to share your tips & tricks? Thanks in advance.
