I have been in a hospital like this. I can’t remember how long but my husband says 2 weeks. My pdoc was a head of the hospital so I was a direct admit. Everyone there was far sicker than me and it was a little scary. Then, I was supposed to room alone but they screwed up and put someone severely manic (I was suicidal and depressed) in a room with me. Moreover, she was hyper religious which I fed off of. They did separate us and apologized to my pdoc and me. Anyway, it was scary but necessary and definitely did save my life.
