Appreciate your kind words and experience, Edwin!
If only my grandmother would give herself the chance to try a home attendant, I'm
sure she'd come around, and this entire ordeal would be significantly easier. That would've been a reasonable halfway point to meet, but there's simply no compromise with her, unfortunately. She's a wonderful grandmother - I could not imagine one who cares more - but her decision is hurting everyone.
Fortunately, I'm on vacation from my job, so I was able to be with her virtually the entire time. My mother and grandfather also took days off from work. When we go back to work, this is going to become far more difficult.
I'm choosing to limit my future job prospects to an area that's in very close vicinity to where my grandparents live, and I will not be taking any vacations that are more than a couple of hours from their place - which means I'm not going anywhere for a long time lol!
