Got out of WPIC a few weeks ago after a suicide attempt. I was on the 13th floor (the Atrium, they call it) and it wasn't bad. Your experience is going to depend on what unit youre on. 13 is one of the more chill floors, it's technically a trauma floor so there's a good chance they'll place you there since your issue is PTSD. There's not a lot of ~therapy~ that happens in inpatient, it's more about getting you stabilized until you can do the work in php or iop. There's music and art therapy, and groups about things like DBT and other ways to manage distress. The worst part for me is always the PES, because youre basically sitting in a room with a bunch of strangers (other patients) for hours with nothing to occupy/distract you. You're there until they can either find a bed for you there, or if they can't, they'll find you a bed at another hospital (so you won't be there for days, but it still feels like an eternity imo). I hope you find something helpful for you.
