Here is a link to an article about schizophrenia.
Schizophrenia is a Chronic Terror Syndrome, Not Genetic: by By Bertram P Karon PhD
I leave you to come to your own conclusions. Here is an excerpt but please read the entire article. If nothing else it will give you another perspective on therapy and the work that goes into it.
“Schizophrenia is not genetic, 85% of patients do not have a first-order relative who has the diagnosis. Schizophrenia is not primarily a physiological disorder, the disordered physiology is the result of the chronic terror. The physiological changes are the same that everyone experiences when we are terrified. Of course there are also physiological changes which are the effect, usually destructive, of the psychiatric medications.
“It is now known that schizophrenics typically have suffered multiple traumas, as well as lesser bad experiences. Most of the traumatic experiences do not get in to the hospital record, but if you listen to the patients you will eventually learn about them. I have never treated a schizophrenic patient whose life as experienced by the patient would not have driven me, or anyone I could conceive of, crazy. People do not get sick because life has been good to them.”
