Although I greatly desire to be of help to you in this well-thought out project for your mental health, I feel totally unqualified to be a lighthouse or anchor, so to speak. First, I have no first hand experience with schizophrenia. And second I have a pathetic understanding of it from my readings.

Although nothing is perfect, I would think that a consultation with one or more psychiatrists and/or psychotherapists would be your best path forward. Perhaps you have had bad experiences in these approaches. I don't know.

Your health, I feel, is too important to be left to amateurs, even well-meaning and well-informed amateurs.

I hope others here will offer things which will be more helpful to you in your great quest which I can't help but admire.
