Do you think that mental health illness can be treated on the theory of insulin deficiency in ? No.

Our psychiatrists have been misleading us by telling us  that mental health is a neurotransmitter deficiency condition just like insulin deficiency in diabetes.let me remind them that many of the diabetes have normal to high circulating level of insulin levels. But the problem is that this normal to excess level of insulin is unable to exert it's action properly in the liver and muscles. So the sugar level in the blood goes up.This is not an absolute insulin deficiency but a resistance to insulin action. How can the psychiatrists propose this model of Type 2 diabetes and maturity onset diabetes mellitus in the young (MODY) where insulin levels are high to psychiatric illness? It's an absolute lie. Another question I would like to ask these pseudo-scientists is that if in absolute or relative deficiency of insulin blood glucose level goes up,then what is the blood-equivalent chemical that increases in the brain due to neurotransmitter deficiency? Or due to neurotransmitter functioning issues at the receptor level. Which would imply that you would be having normal serotonin level yet you are depressed. You maybe having excess dopamine, yet you are unhappy.
