Most people attribute the distinction of mind and body to French philosopher Rene Descartes. Descartes believed that the mind and body were distinct. In other words, he believed that the mind and body were independent of each other. His mind-body dualism has been disproved many times, yet it still survives. For example, moving limbs (or a reflex) and our sensory organs disprove the thesis. Thus it's a false premise to divide health (physical and mental). In truth, there is only health.

I hope that in the near future we'll view diabetes as similarly situated to depression.
