I have not been, but as others have stated, it can be very liberating. You get out of your regular jacked up environment which is likely stressing you out, and you get to focus on YOU!

Honestly, until I started going to DBSA groups, I had a negative view of hospital stays (because I hate them for physical ailments) but many who had gone said they were the best thing that had happened to them. I would go. Please keep us updated on how things are going. I've been where you are, and it sucks. But it can get better.
