Hey it might be a good idea to post this in the schizophrenia forum as your article said paranoia most often goes with schizophrenia. Just a suggestion.

And then there is psychosis. Once I was manic psychotic and I was terrified people were looking at me in the ER waiting room. Well they were because I was screaming! But psychosis is different...I was seeing things that weren't there...either that or the veil between this world and the next had been lifted and I was seeing the other side.

I've seen crack heads that were severly paranoid. Not a fun drug.
