In support of psychiatrists - They all have a very difficult job to do in diagnosing mental disorders. Some people are pre-disposed to a condition that other family members suffer from, some are drug/cannabis induced, some are the result of a major shock or long term stress. There is usually a trigger of some sort.
I'm sorry to diagree with you about the hearing of voices. I can assure you that sufferers of schizophrenia DO HEAR VOICES, that is one reason why so many of them have to listen to loud music or tv in order to drown them out. If you had someone banging on in your ear incessantly, day in & day out, you'd probably do the same.
Of course every person is an individual & exhibits differing symptoms at any one time, but over a long period, people suffering from this illness WILL exhibit most if not all of them, and that is the reason Doctors initially give a blanket diagnosis. & treat with similar drugs. As the patient settles down, their treatment may need a change or refinement of the medication & a different diagnosis, but this takes time.
All psychiatrists have their own ideas & some are a lot better than others, some you'll like, some you won't, but they are the best chance you have to get better.
As an awful lot of tablets we take every day are capable of killing us & have sometimes profound side effects, but until Medicine can find the answers or come up with a magic cure for everything, most people would opt for something that will relieve the worst of their symptoms & allow them to live in some sort of normality.
You can have all the experience you like as a professional, but until you've had to live with the illness every day & every night for 26 years, you only view scizophrenia as an outsider. Medication to control Seratonin & receptors in the brain is the only treatment available at present, but that must be backed up by support for living as normal a life
as possible in the
