I was only ever in private psych places, and believe me, those were bad enough.
24 hour attention/watching, lot of noise, including crying and screaming, some staff are power freaks and will take every opportunity to use power ( I was shoved to the ground and sat on when I was very thin and had only been trying to get away).
I was even stitched up without any form of numbing.
And I have heard it is much, much worse on wards in the general hospitals. A lot of abuse goes on. You lose your rights. It is a living hell, I can tell you, and I was only kept in for 6 weeks. 6 weeks too long. It is not like the order and routine you get in a normal hospital ward.
