Hello Pika,
I just came across this post and send my reguards. Hoping all is well you and yours. Not easy to care for others but it's something a persons gotta do, especially when it's someone you love. Although every situation is different, I think the best thing any caretaker can do, would be to take care of themselves as well. Tough to do in certain situations. My wife and I had to go through it a few years back with her parents and it was the toughest hike of our lives, mostly her's. I was able to find an out in my job and of course this site. Best wishes

Bruce
