In - My - past experiences with hospitalizations it was the therapist that did the involluntary commitment and or brought up the issue when that therpist felt - MY - being hospitalized would benefit ME.

Also many of - MY - friends go into a hospital not just for stabilization they go into them because the facilitys can offer more in dept treatment options for example a person does not have to be unstable to enter Dr. Colin Ross facilities that teach clients how to manage their Dissociative Identity disorder (what DID is, What to do during flashbacks, panic attacks, losing time, getting lost, and so forth,) and work on in depth co consciousness and integration if the client want that.

Basically entering a hospital setting depends on what the client needs.

Local hospitals have a mental health unit for stabilization and a few group therapy options like the ones I was in had anger therapy group, depression therapy group, relaxation therapy group, drugs and alcohol therapy group, and one support group

Then there are specialty hospitals like Dr. Colin Ross facilities that work on specific disorders and problem.

So basically its up to you and your therapist if you need or want a hospital setting and what would benefit you.
