I've been inpatient twice.
where I am there are separate rooms (the old hospital with ward bays was shut down and the new unit is much better) with en-suite bathrooms. room doors were card entry so nobody but staff could come into your room. the bathroom doors were open top and bottom so you could be watched if on obs. the bedroom door had a window with slats (that you couldn't close) so staff could do night checks.
no safety razors, no phone chargers and no lighters/matches permitted. phones were charged down in the locked property room and razors only given back for showers.
meds at breakfast, after lunch and bedtime. diazepam etc as needed if you were written up for it PRN. smoking permitted in the (secure) garden. the food was really good. tea trolley was the highlight of the day as it only came out every couple of hours.
where I was there was no therapy at all. tv was on permanently - the 'welcome' pack said it would be off during the day but this never happened. there were board games and cards etc but I was too zonked on meds to get to grips with them!
the people were mostly lovely once I settled in. it was very scary to begin with but I ended up being ok wth being there - I was in for a month the first time and a week the next time.
the problem is that with no funding, psychiatric units are just warehousing rather than therapeutic. lots of bank staff especially at night - with no motivation to do anything but light our cigarettes and watch telly with us. day staff had so much paperwork it was ridiculous.
if I needed to go back I wouldn't hesitate. just being away from the pressure of my life for a bit was really helpful. it meant I could start new medication under observation, rather than potentially struggling at home with only visits from the Crisis Team. additionally, my husband at the time was a prick, and it was a relief to be believed and supported through what was a complete breakdown. I'm still not back to work etc some 4 years later. I am however divorced from the XH so silver linings and that!
honestly - it was mostly boring with occasional flare-ups and fights. I didn't want to leave the first time I was in.
I hope you're doing ok, OP. it's not as scary as movies and the media would have you think.
