Oh, and I worked at a psych hospital. The units that have the out of control, or not yet controlled people, schizophrenics, or sometimes bi-polar can seem very “crazy.” it is not that the whole population in there is ranting or acting out of control, but there are more of those types there. Those units generally smell bad too, like urine or BO. Having said that, I worked on that unit, and so did many young women, we felt safe enough to work there. I only mention we felt safe because I worry my description sounds scary, and I did not feel scared. Many of the patients were very nice, wanted to feel better, it was sad.
Other units are calm, could be any hospital, the only difference is you are locked in. People who are depressed, not coping well, etc., can be anyone, a friend, a family member. You could meet the same person anywhere, at work, in a mall, through friends.
