He is 94, has dementia, frail but stable medically. He is blind, can walk. I work part time as a nurse and we have other caregivers come in when I am gone. He misses his home and family/friends back in Michigan. I am afraid to take him back for visit. The plane ride get to my home in Oregon (2and1/2 years ago) was somewhat harrowing, but he doesn't remember that. I am afraid that if he doesn't get up he will lose his ability to get up. He also has a brother in Texas and an uncle in Florida that would be fun to visit, but I'm not sure I could manage all of that. I am 71 and it makes me tired to think about it.
And if your dad is refusing to get out of bed a trip to visit family by plane is probably not doable anymore.
He's 94. He's tired. He has dementia. Maybe he's just run out of steam. At his age it's bound to happen eventually. This could be the new normal for him and for you.
