In my mid twenties, I had a psychosis that lasted about 14 months. It started with auditory and some visual (distortions) hallucinations. About 6 months later, I became delusional, paranoid and agitated.

The agitation was very difficult to deal with. It was so severe, I mentioned it to a social worker, I knew. She set up an emergency appointment with a doctor, who diagnosed psychosis, and prescribed Zyprexa. Within three days, I noticed an improvement, especially with the agitation.

I think in the early stages of psychosis (before the delusions set in) one can have insight. As it slowly worsened, my insight became less and less.

At the time, I was diagnosed with Psychotic Disorder NOS. It hasn't re-occured so I consider myself recovered.
