I don’t understand what Sean expected out of a long term care facility. Unless someone cannot get better, long term care is a road to independent living. Even some of my relatives (nursing home residents) that were clearly never going to improve got daily physical therapy with a goal (pipe dream) of going home.
He hated the hospital, especially the diet. He hated rehab (arguably a long term care facility). Did he think a nursing home is going to take someone who could be able bodied, then not rehabilitate him/her, thus turning away someone unable to care for himself/herself (or many someones, over time)? Did he think a long term facility would have giant beds, unlimited food, 24/7 attention, and private rooms, all, somehow, magically leading to weight loss?
I legitimately don’t know what he was imagining in his mind.
Honestly, I think he wanted one of those adult baby/caretaker relationships, which are usually considered a sexual kink, but from my (VERY removed) understanding, are usually non sexual. Not saying that would have been good for him, but I think it’s the closest achievable situation to what HE considered ideal.
