Well here is the thing...nothing in your posts really suggests paranoid schizophrenia to me. You talk about an alter ego that you have control over and while you suggest it's not did it's kind of like compartmentalization which isn't a condition at all. But we can't diagnose here so let me put your fears to rest regarding the somewhat overly dramatized potential outcome if you do find yourself with sz or something related.

I took meds for 3 years and while I was less emotionally expressive I also felt less irritated by and more connected to other people than I ever had before. I have a PhD and work on curing disease at a local university hospital...while I'm not rich neither am I poor. I own a condo near Chicago and drive a blue volvo. In general I consider myself to be a good person and I try to use my life to help benefit others. I have the same job I had for the last ten years and it was my boss and coworkers who took me to the hospital for help. As far as the hospital goes though I would not recommend it unless you are planning to kill yourself or someone else as it's primarily a holding tank to wait for meds to work and by far the most boring and controlled environment I've ever been in....

Hopefully I have put your fears to rest.
