My only experiences with being an inpatient were at least 20 years ago. Things may have changed generally since then. Mine was done "voluntarily" -- at least formally. My experiences were not helpful. They have left me with a great aversion (read fear) to the thought of such hospitals. Their "transparency" as to what they were doing was never apparent to me. They did not explain things in a way that could be believed; it was always made out to be more "wonderful" than it really was. All problems seemed to be blamed on the patient -- or explanations were avoided, letting the patient draw that conclusion.

As I said, maybe things are generally better than they were in the past; maybe people are more honest. Or maybe you can deal with their deceptions, even their self-deceptions, more than I could at the time. It probably does depend very much on the individual hospital, and on your state of mind, how well you are able to cope with what you may encounter.

And as some have suggested, much of the time in the hospital, at least in my experience, was not spent in anything that could be called a formal "therapy". Lots of "hurry up and wait".
