There is a moral imperative to seeing mental health through the same lens we use for other pathologies or illnesses. Being sad or overwhelmed is normal, much as being short of breath after a run is normal. Both become abnormal when they happen with no apparent cause and are hard to stop. Those situations need medical attention.

Sometime they don't let you know that they know that they don't know everything but the core of the medical approach is that you try to identify pathologies which are subsystems within the human body or the larger system that are having undesirable consequences.
