Your own savings reason says it all....
Don't be coerced, bullied or trapped by them wanting the bed emptying and not wanting the effort and bother of getting a residential placement.
Not easy for him, his conditions, age, frailty and fears, not nice at all and then to be told to go into residential and not return home will be awful regardless of anything beforehand. But if it is what is needed for his care then that is where he is at and where he needs to be. I can't begin to imagine how that would feel, and then you will have to bear the brunt of it while he adjusts and deals with his issues about the situation, but that's what they are, his issues. Upsetting to see and to receive the anger but you are visiting and can remove yourself from the situation to powder your nose or go home.
They will be adamant on him coming home, the best in their opinion is for the patient to return home.
But best for who? Not the patient if you can't supply the care required or if the effort puts you in hospital! Could be trying it on, could be shortage of residential home spaces. Not best for you because it is too much for you.
I've noticed of late that the physio/occ therapist phones to say discharge and basically every time I find they have been somewhat creative about her physical ability, one of which occasions they were reported for an unsafe discharge by me and by the homesafe team.
Good luck tomorrow.
