Glad you're out!! Strange happenings in that there hospital. I would write the mother of all complaint letters to the Hospital, cc it to as many a possible: CEO, CFO, Medical Director, head of Nursing etc...Talk to the CA state dept of Health, and file an official complaint. Sounds like they left you with some emotional scars.
Sounds very strange that they gave you so much Ativan and wouldn't let you out of bed. Hope you get some resolution to all of this.
Take Care
