I'm sorry. I hate running into it too. That's why I hide who I am, that I'm a person with "mental problems"... my relationships suffer for it. I feel that I'm unlovable, in part because people ACT just like the way you're describing if they know other people in similar situations.
and no, when I was psychotic... I couldn't really control my actions. That was what scared me the most about it. I almost never got "truly" psychotic... I was right on the brink of totally losing control. The only time I was "fully" psychotic, I was rolling on the floor unable to stop, due to psychosis brought on by psych medications that did not work for me. So no, I don't think someone in a psychotic state has control. It depends on the person and the type of psychosis, but ... yeah. I sure didn't. It was so scary, I still have nightmares about it years later.

OK, Pegs... good news is there are a very limited FEW WHO GET IT. Hang onto that fact
