Thank you all for your comments.
A few months ago she had a precursor stroke. A “you really need to check your blood pressure or it really WILL be a stroke” precursor stroke. She has changed her diet, has been getting more exercise, and is taking meds for her cholesterol and BP. Sadly, other than a few very elderly assorted great aunts/uncles, she is the only left of her family. Her mom died at age 59, her brother died when he was 59, and her father died at age 80- but had Alzheimers. When we celebrated her 60th birthday she said “That’s it, I can croak now”, because she honestly never thought she would make it to 60. Now she’s 66. She and dad have been together for over 48 years.
My sister and I have tried talking to her about slowing down. Having her sister-in-law in the house is very stressful for her. Auntie forgets to bathe, to change her clothes, to eat. When mom reminds her to do stuff, Auntie yells at her. And it’s not as if it’s a short visit- Auntie will probably be here until early July. As Auntie has started slipping, Dad’s other siblings have disappeared. But their decision to have her was THEIR choice. I know for a fact Dad was against it, because he knows how it wears Mom out.
I also don’t know why she is always babysitting their greatgrandkids. My nephew and his fiancee earn enough for a babysitter/daycare, but mom offered. OK, fine. They lived with my parents for a while when the hellhole condo they bought from me fell apart, and it tired mom out, yet for some reason she believes that SHE must be the one watching them. The oldest child has anger management issues (at age 4) and is in counselling. She is over at their house at least 3x/week, often overnight (even if my nephew is home and the kids could be there, my mom doesn’t think as a male he could take care of them). I think it’s great that she does it, but it’s at her own expense.
So yeah, she has a lot on her plate. When LilMiss was, well, Lil, she was Gramma’s darling. They watched her a lot during the summer when I couldn’t afford FT daycare and it was beautiful. Serious precious memories. But as LilMiss has become older and has been able to form her own thoughts/make her own decisions, Mom has become meaner to her only. Everything LilMiss does is treated with disdain. They picked her up from school last Wednesday. LilMiss had her report card. Well, last semester she received an “N” (like a C or D) in Science because she didn’t turn all of her work in. We dealt with it and moved on. This report card was pretty decent, almost all S+'s (A’s, I guess). Mom harped on about last semesters lonely N. LilMiss had brought the N to a S+. No comment on that. Just that she had an N. When LilMiss pointed out that it was last semester, and look at it now, Mom replied to the effect that you do NOT interrupt your elders and that what would LilMiss know about it. Uh, it was her fucking report card?!?
Mom and Dad came back over a bit ago. Mom said she and Auntie would be at LilMiss’s concert, but stated she didn’t understand why it was a big deal, it’s just elementary school orchestra, and that she is not happy about having to bring Auntie. I simply said “Thank You”. We’ll see how it goes.
