This is normal in my part of Canada. You just have to stop being a danger to yourself or others to be discharged. Doesn’t mean you’re close to functional and able to care for yourself. Anyhow, the bed has to go to the next person who is in worse shape than you and we have a backlog of those around here.
Last time I was hospitalized in 2015 I got released to a temporary transition house for people as an alternative to hospitalization or for people who had just gotten out of the hospital like me. We had chores and groups and classes. I had just finished living on my own for twenty years in normal society, usually renting rooms in peoples houses. I stayed for a week at this house then I was back in a board & care.
In 1988 I was in the hospital for five days and then released to go back home, living in a small studio by myself. There was no smooth transition that time, I got out and I was sick, weak and shaky, it took me several days to recover.
In the UK you’ll get more help and support if functioning 100% most of the time and <25% the rest of the time, than if functioning at 40% level all of the time.
