All I can do is re- iterate what's all ready been said. I'm schizoaffective and it Is biological as I need medication. I just happen to have had a not so privileged up bringing so I drunk to excess and brought on my psychosis earlier than if I hadn't, or it was more acute, it probably would have happened about same time it was inevitable but I made it worse with alcohol. I think trauma can make it worse, and of course stress is a trigger, I get racing thoughts if I am stressed. Since every day is different i managed to wrangle some extra daytime meds for when i do get an extra stressful day.
