Yeah, I'll get paranoia when I am stressed or off my meds. Though, sometimes when I *am* on my meds, I will still get paranoia. But I get psychosis all the time, mostly in the form of mild hallucinations. I actually had some hallucinations last night (voices).
I am not Dx'ed with SzA and the diagnosis doesn't fit me, despite having psychosis independent of mood episodes. (I'd say I have psychosis 50% of the time when things get stressful.) I don't have catatonia or word salad or anything like that. Schizophrenia symptoms wise, I just have attention/concentration problems, flat affect, flat vocal tone, and tangential speech.
