Been there, done that. No real intention of doing it, mine was from PTSD, too.
Got trapped in a run down, fly infested hospital for 6 days. The first 3 were in the emergency room where I got to watch a woman attack a bunch of people, get put in a straight jacket, and got injected with something.
3 days surrounded by violence, screaming, howling. Never saw any doctors. They tried to make me take random medications with no diagnosis or instructio s, which I refused.
Then I got put in the drug rehab section. It was mostly homeless heroin addicts there, plus a few old people who had shitty families. Watched one old woman's condition deteriorate after they kept feeding her the random coktail of medicine they tried to give me.
I told one of the nurses I had PTSD from getting kidnapped and tortured, so that night she played this bizarre kidnapping/torture movie in the common room.
People were kept there for weeks, sometimes with no explanation. I only got out because I threatened to sue them, and since I had a law degree, I knew all the right words to scare the head doctor.
I begged them to let me leave because I had gone in job interviews and was waiting to hear back. The minute I got home I had a job offer waiting for me, and I accepted.
What a fucking nightmare that was. I'm keeping my problems to myself now, and I'm sure as hell never trusting doctors or hospitals again.
