I think you are unnecessarily suffering guilt symptoms. My Mom came to stay with me at about age 88 and she used to go to one of the local Aged Care Centres twice weekly, out of her own free will. There she attended Church services as well as outings and other suitable entertainment with people of her own age. She used to tell me she wished she could get a permanent place there but I was having none of it, due to the very reasons you have stated above.
At age 90 she had lens implants in both eyes because of cataracts. She was elated, she could now see clearly and read newspapers once again, with out the need for a magnifying glass.
At age 93, she tripped and broke her hip. Doctors told her that she would now be relatively immobile and would need a walking aid or wheelchair to get around. Yeah, right! She used to carry a tray with a mug of coffee and plate of biscuits in her one hand, while carrying
her walking stick in the other, and even step over the cross Ridgeback-Boxer I used to have.
At age 95 the doctor advised that she be placed in a frail-care centre. This was the happiest day of her life, she was now going to be with her friends at long last on a full-time basis and could not wait for the day we took her there. She lived happily there for over two years, we had a surprise blast for her on her 97th birthday.
Three weeks after this she quietly slipped away at Hospital, where we had taken her because of low blood pressure. But she had a brilliant life, right up until the very last day! In fact, more so, because she wanted
to be at Elandshaven Frail Care Centre.
