Newtus, I can totally relate to your distress about hospitals and feeling controlled by drugs. I can't tell how you will feel about Haldol, because it depends whether you feel invaded or helped by the experience. You may get used to it.
I hope you find something that helps you.

I tried my absolute best to appear normal in my daily meetings with my pdoc in hospital, in order to get released. It wasn't quite lying, but I sure wasn't keen to tell her about anything she could possibly interpret as signs of illness. (She had blackmailed me into "voluntary" hospitalisation).

I believe one of the best ways around the feeling of paranoia is having a pdoc who can validate your experience, rather than simply squashing it with with a sedating sledge hammer. I believe our responses to these drugs are quite different if we experience trust and compassion rather than mechanical processing in our relationships with our medical team.
