Invisible illnesses of all varieties are a plague on mankind. Those who suffer it know this all to well and those who don’t often choose to ignore, or worse yet, deny that such illnesses exist.
Ironically many nay sayers develop symptoms themselves. Arthritis, hay fever, and headaches are all common invisible illnesses. Only then, these problems are to “real” illnesses. Funny how that works. Many of these will choose to do their best to ignore the problem in the irrational belief that it will go away or fix itself. Furthermore, they extend concepts to others who cannot do the same.
The medical profession is at least sometimes part of the denial process. Often it takes a lot of time and effort to dx complex problems and practitioners simply don’t have or, won’t take the time to understand let alone treat people with invisible illnesses.
What a tragedy.
