Mental illness needs to be treated professionally rather than society indulging these individuals with their delusional fantasies, it's not healthy and sadly, this will only get worse as we are being pressured by fringe minorities to accept their warped and distorted realities (think furbies or this school girl who identifies as a cat)
I think it is extremely condescending to diagnose “mental illness” from an article: you don’t know the person and no professional should diagnose an illness from a secondary description of facts.
Also, the article says that it helped him with “deep depression caused by work and fear of social rejection” (sounds situational, not a clinical diagnosis). Relevant discussion about OCD: “half the psychiatrists at my hospital thought this was absolutely scandalous, and This Is Not How One Treats Obsessive Compulsive Disorder, and what if it got out to the broader psychiatric community that instead of giving all of these high-tech medications and sophisticated therapies we were just telling people to put their hair dryers on the front seat of their car? I, on the other hand, thought it was the best fricking story I had ever heard and the guy deserved a medal. Here’s someone who was totally untreatable by the normal methods, with a debilitating condition, and a drop-dead simple intervention” - https://quotulatiousness.ca/blog/2016/02/02/qotd-the-hair-dr... from http://slatestarcodex.com/2014/11/21/the-categories-were-mad...
