Yep just like fibromyalgia and chronic fatigue syndrome, both affects …certain types of personalies but also people with long histories of poor physical and mental health (which is trendy to get over-excused these days as being without any personal responsibility but there's still plenty of people with serious personal backgrounds where it's difficult to pass judgement). But ultimately the appearance of symptoms doesn’t make it an illness. Still a “syndrome” is better than “mass panic”.
