Been there twice...yeah, pretty much what all the other great posts said, but I will add this:

You will get asked the same question or series of questions by up to 10 staff members daily!!! (I thought...then I asked..."Do you people not even read charts and communicate???)

Also, you may be given a "battery" of tests, (up to 1,000 questions) whereas within these "tests" the same question will be asked to you differently up to 30 times.

The staff may appear as prerecorded robots, as they will sing the same tune to you..."Accept...Cope...Refocus"

You will attend Group Therapy (which I hated)..where they will encourage you to share your story with others....BUT..during admission...they tell you, "Oh..all stuff is confidential." I live in a rural area, so had I shared my story with "others"...I may as well had placed it in the newspaper. Also, and this was a good thing for me...Group is usually dominated by some long-winded patient who can talk the red off of a stop sign....I enjoyed them!!
