Update-
"She who adores me" is feeling much better. She insisted on doing some housework yesterday, in spite of me telling her not to, and we went out to eat BBQ last night. She's out getting her hair did today, so that's definitely a sign of normalcy with her.
Blood pressure is good since getting her on medication for it. Might not even need it once all this is behind us. This whole thing is due to stress.
One of her sisters has found a memory care facility that is looking very promising. The hurdle now will be to convince their father to go along with it, which is not going to be easy. But we're all gonna go see him and try to make him realize it's necessary.
So there might be light at the end of the tunnel.
Thanks again for all the prayers and well-wishes.
