My recently widowed mom, 76, was just informed by a social worker 1. that her brother is terminally ill, and 2. he has directed hospice to my mother's home. She was shocked. Can he do this? He's difficult, stubborn and knows my mom is a soft touch. She cannot manage him, which he knows. I believe he's decided that without her husband around, he can just move in and have her cater to him in his final months. The siblings are not close. Mom only sees him when he needs money. The social worker says he is "self neglecting." He refuses to bathe or eat.
TBH, I feel bad having told you to urge your mom not to take him in, because it turned out he only had a few weeks.
I don't think caring for someone who won't bathe in a private home is feasible or sanitary. Especially not when the caregiver is elderly and frail herself.
I see this situation to often, terminal people will not accept it and hospice isn't called in until the later minute. It breaks my heart how stubbornness cause people to suffer needlessly, and their families.
I am sorry for your families miss and pray that The Lord gives you all grieving mercies and comfort.
