1) mechanic-like workmen in the classic mold of the "blue collar" work ethic but don't pretend to be better/worse than others. Often produce better results that the "IQ" tests would suggest.
2) Usually competent but imposter syndrome people that sometimes lose focus due to lack of faith in training and ability. Capable of high achievement (probably better than #1) but often struggle with consistency in end results. Often undersell themselves, so it's hard to tell if they know what they are doing.
3) Status seekers that hide subpar ability or even downright incompetence with degrees and arrogance. Kind of a high functioning "Dunning-Kruger" subtype with conman/sociopathic /social abilities.
4) The frighteningly competent that case #3 pretend to be, #2 might be able to do, and are basically #1 combined with real talent.
Sounds like you ended up with #3.
Whenever I encounter an "expert" in a field, it comes down to diagnosing whether they are a 3 or a 4.
I'm a programmer and I'm an average #2.
#3s in programming are kind of different. Incompetents get weeded out quickly from true programming jobs and punted up to management likely where they become part of the Middle Management Machiavelli perpetual war.
#3s express themselves as moderate technical competence, a typical one would be someone that gets to declare greenfield to the specific stuff they have enough ability to do, gain sheen of competence, and then aggressively assume the role of "expert" based, since to management they "produced".
Next thing you know, some guy that could rapidly stand up a PHP site is in technical leadership and pushing for PHP to serve as a big data platform because it is (rolls another dice to determine buzzword) "agile".
Then they have as much or more organizational pull as a legit #4 and your organization is in TROUBLE.
Of course many of these indivudals are self diagnosed but that doesn't stop them from talking about it constantly and holding themselves up as a "suffering soul". Meanwhile those who legitimately struggle with issues like depression or anxiety now get either brushed off, or have people that "totally understand" when really they don't at all.
Also, the same mental illness could have 20 different causes, and a method which cures one of those causes is ineffective against others.
The people with mild illnesses need help too. The people with more serious issues need more serious help. But when someone says “I’m depressed” you don’t know if they’re a little upset or genuinely miserable. You don’t know if it’s because they’re life is boring right now, their dog died, or there’s a serious chemical imbalance. So in essence, saying “I’m depressed” no longer means much unless you state the symptoms.
I have/had Tourette's (like most, I grew out of the worst symptoms after adolescence) and the media portrayal of it is pretty awful. These symptoms align with the portrayal, not the reality. Tourette's should be diagnosed by a neurologist, not a GP, and this doesn't sound hard to distinguish.
Suicide is also a social contagion. So are eating disorders, depression, gender dysphoria, cutting. All documented occurring online and obviously occurred offline pre-internet, perhaps not as well documented offline.
These people are all suffering.
You can't not talk about it. You have to work out how to treat each disease correctly.
