Hi-
I had a PA TRY to force me into an inpatient unit.

This woman was very aggressive and about twice my size (which frightened me that day)...I was just there to advise the GP that the Zoloft was causing side effects. She had me in the exam room for about an hour- I was crying and SO anxious...she said something similar to "You know you are crying as you know I am right. Let me call the ambulance now.". NO. An inpatient unit would have destroyed me as I am agoraphobic and do not want to be around people. She did ask me if I felt like hurting myself. I will always say no.
Of course I have thought about it, as you said, as a concept. I have no plan, if I did, I would have been gone a long time ago.
