I had a very very horrible experience when I was in a psych hospital, this time last year. It was an abusive atmosphere (and I am talking about the staff not the patients). They would lock the bedroom and toilet doors for around 5 hours (their explanation was for cleaning purposes) this resulted in patients having to resort to urinating in the garden. When I tried to talk to a nurse about my suicidal feelings she deemed me 'selfish'.
I could go on and on. We did put in a huge complaint straight away and had a meeting with some top dog, but I still have extreme anxiety about my stay and it has made making any further contact with my MHT very hard as they are based in the same building and I am terrified if I went to them when ill I would be admitted to that ward again.
I saw a lot of abuse directed to one patient in particular, a nurse walked up to her one day and actually shouted "BOO!" right in her face....I still wonder what happened to this poor girl. :0(
