Since most people take modern medicine as "absolute" (by saying that I mean, people believe modern medicine can take care of all physical illnesses, except fatal diseases like cancer), they easily consider the cause of unknown illnesses as "mental". This is why we often see people try to "encourage" those who suffer invisible diseases to work "harder", to push through, as if they are mentally weak individuals. I still remember once a kind lady's first words to me after hearing my brief story: " be tough." I have to say, not only this is a wrong approach, but also offensive attitude toward those patients. Why, because one of primary reasons these people got so sick is precisely because they are mentally tough - so tough that they overdrew their energy, and their illnesses are nothing but the consequence of their mental toughness (physical energy overdrawn).
