Hi w_i,
We've done inpatient six times during the past four years- two of which were 'planned' - i traveled across the country to a hospital that had a trauma unit because a friend online had recommended them.
They were helpful a little - i don't think it made a big difference in practically helping me other than to keep me safe and distracted at a time when being home was not a good idea. It was a struggle to save to money and travel alone- and a huge leap of faith.

There was a very bad stay at the hospital where my T works - in trauma unit. i had an 'old school' dr who thought it was a good idea to put me in isolation (or she didn't understand why i was acting out- isolation made me so much worse) . i became so destabilized when there was nothing to ground to- no one to talk to for days and days in a row. It was the worse time in my life. My parts have their identity from the people and places we live in. When away from everything we fell apart- further each day.
There were many other people, mostly other women, at that hospital that had a 'good' stay. They were allowed to go to groups, learn coping skills, journaling, etc, there was therapy everyday. There were classes like exercise and art.
i've never done well inpatient because my parts need their surroundings to ground.

If you need to be safe then you should go anyways.

Take care,
kerria
