You can have bipolar and psychosis without having schizoaffective.

I've had many psychotic episodes. The first one happened before I was diagnosed, I got on the subway after work and every time I met someone's eyes I could hear their thoughts and they were telling me to die. I almost went through with it but went to the hospital. The second time it happened was in the hospital, I believed that by not killing myself that day I had broken free of destiny and anyone who came in contact with me would be hurt.

And that's just two of them. There are others where I would discover special messages or the power to heal people, etc.

In general though, I haven't had bad hospital experiences. The last time, two nurses forced me to go through many many needle pokes for a blood draw, including one that gushed blood because her hand slipped, but there was nothing personal about it, they just wanted to get their job done and didn't care if it caused me distress. She just couldn't get a blood draw, tried several times, and when her hand slipped and blood went everywhere I tried to refuse to let her continue but she and another nurse basically forced me to let them keep going until they had the blood. It took at least 8 pokes and digging around on both arms combined. The next day, while still inpatient, I complained to their superiors and learned they were supposed to stop after 3 tries and wait until the next day. But again, it's not like she personally wanted to hurt me. She just wanted to get her job done in one day instead of having to pass it off to tomorrow's nurse. I complained, and never saw her again. I put the experience behind me.

The only thing that made me uncomfortable, again about the last hospital experience, was that they would often lock the far end of the ward to keep wanderers or upset people inside, and my room was in the far end. They offered to lock me in my room for my own "safety" because of the other people, but I refused and sat in the dining room all day instead.
