I would say that everyone has various traits that can fall into unhealthy levels. The majority of general population don't carry extreme levels of the traits though.

It can feel as though everyone has emotional troubles. And to some extent, that is true. We all suffer in life. Some of us to more dramatic degrees than others though. And we're the ones that tend to suffer a variety of mental (and physical) health issues.

The illnesses are real. They can cause a lot of pain, suffering, confusion, and inconveniences. It's better that the general population has some degree of understanding the many illnesses that affect millions of people. This understanding leads to a lot less hurt feelings and allows the disabled to still play a part in their communities without feeling like some dark plague, feared by others.

That's my personal perspective.
