You are making an assertion that has no bearing in evidence. That is an industrial more, not a medical fact.

There are many therapists who do not use drugs at all and many patients who have recovered without needing to be sedated by brain disruptive medication.

Dr. Peter Gotzche of the University of Copenhagen released a comprehensive meta study of the effectiveness of psych meds and concluded that beyond acute intervention, with a withdrawal plan to limit withdrawal symptoms, including withdrawal psychosis (which is often blamed on the "disease"), these drugs are far more harmful than helpful.

The insulin analogy does not hold. It can be demonstrated via empirical medical testing that somebody's pancreas does not produce insulin.

There is no reliable bio marker for any current mental illness, but rather a vague definition of certain behavioural clusters that are then termed illnesses.

It is quite informative that the National Institute of Mental Health in the US has stopped funding the APA and DSM criteria because they have no medical relevance whatsoever.

This goes without getting into detail of the admission of almost thirty years of misleading the public about the chemical imbalance myth. It has since been discovered that this myth was developed for two reasons: compliance and marketing.

Further, if this model was effective, the incidences of diagnoses would be expected to taper off at some point and out of the 300 odd diagnoses, at least one would expected to have been cured by now if there was a biomedical cause. This has not happened.

I could go on about the fraud convictions that have befallen pharmaceutical companies and psychiatrists world wide, the fact that homocide and suicide are documented side effects of many SSRIs and Benzodiazapenes, the role of regional trends in diagnostics and the admitted problems with relying on clinical subjectivity without any mechanism for bias correction.

In short the biomedical model of human behaviour is a bunch of horseshit, regardless of how embedded it is in society or the comfort it provides some to think that their behavioural and coping issues are caused in the same way as the flu.
