From my experience the main way to get a diagnosis of schizophrenia is to be associated with violence in some way. You may have been a soldier or maybe just a youth cadet. You may know a martial art. You may, as,I, have done research in the defence industry. Having signed the secrets act I wrote software to aid in the design of nuclear engines for submarines.
The only problem is you do not talk about it to medical personnel. They are in that profession because they have a primary motivation for healing, caring, to do no harm etc.
I know it is odd that such people should judge the character of all society without trial or jury but that is the reality.
So to them you have no knowledge of violence. If you worked in a defence company you do not mention the weapon produced. You just did engineering. If a soldier you just did peace keeping. If you were assaulted and defended yourself you mention only you were assaulted.
Detach yourself entirely from association with violence. These people only get blamed if the patient hurt someone and they showed signs of a violent temperament. So they will make you docile with medication to cover themselves and give you a stigmatizing diagnosis. So if anything happens its oh he was a bloody schizophrenic. There is no such illness.
I am now classed as in remission. For the simple reason I never talk of violence. I still spout my #######4 theories on any subject under the sun. But no one cares what rubbish goes on in your head as long as you have no capacity for violence. Hell go the whole hog and wear a peace badge. The world needs people who are prepared to do violence to protect. This new psychiatric cleansing of them is probably why a group of tribesmen from the poorest country in the world have still held out.
Camouflage yourself. Peace.
