A lot of so-called adults use these diagnoses as an excuse for their shitty behavior too.
I heard recently that an ex friend of mine recently told people that she thinks she's autistic. Yes girl, it was the autism that made you do and say shitty things behind people's backs. lol.
Because of social media creating social contagion, people are misconstruing personality traits with medical diagnoses. It's insane.
It's also stupidly easy to get diagnosed with most mental illnesses these days. The current state of the mental healthcare profession is absolutely laughable. The current criteria for diagnosis is so broad, that if you gave me a copy of the current DSM-5 (or whatever your preferred diagnosis manual is) and 15 minutes alone with any given person in America, I could get you at least one diagnosis plus autism for every single person. You can probably add a free ADHD diagnosis for all men as well.
I absolutely loathe that things that used to just be personality quirks are all listed as symptoms of some disorder these days. It makes all professional diagnosis useless. The best diagnosis for genuine autism isn't from a mental health professional/doctor these days. It's from watching the person act in public and interract with others to see how awkward they are.
Like to stay focused on one task? Prefer routine? Narrow list of things you show genuine interested in? No, you're not just a normal male, you got Austism!
I think there's technically a clause in there on most disorders that says something to the effect of "These behaviors have to significantly impair the life of the person to meet the criteria for diagnosis" or something, but 99% mental health doctors seem to ignore this part. After all, they can't get money from repeat visits or writing perscriptions if they don't diagnose you with
something. Nevermind that a ton of people these days
WANT to be diagnosed for free pity points, asspats, or to have an excuse for some failing in the way they regularly behave.
