It's a usa thing. Their psychiatric wards apparently also provide like actual therapy and psychiatric help too, from what I've read.
I don't know what it's like elsewhere but in the UK, psychiatric wards are filthy, underfunded holding pens run by the dregs of the nhs. And you get no help, just held till they arbitrarily decide if you're 'safe to be released' or not. You don't get socks here, you get ptsd.
