I'm not even here to argue this point. Even if it is true — I so don't care.
When I was around 15 maybe, was the first time my mother told me I might be autistic. I cried and locked up in my room. Not because i thought autism was bad or shameful, but because i didn't know it was an actual diagnosis. At school, all the social circles I've been in, autism was a slur with barely any meaning behind it. It was for "stupid", it was for "lost cause".
So when i heard my own mother call me that, that's what i thought she meant - a lost cause.
Yes, it's annoying to have people misuse the terms and call themselves neurodivergent when they're not. But i rather have this, than have people feel the same way i did that day.
Depression also used to be seen as something performative, as a label to be not like others, cool and mysterious. But as far as i observe — people who were pretending eventually just moved on; people who were in fact depressed, learned the word for it.
I was a teen exactly when "depression is cool" spiked, and very short after "pretending to be depressed for attention is cringe". So when i was thinking i might be depressed, i told myself I'm faming it. Turns out i truly was. And even if the people who were faking it did make me reject the thought in fear of being one of them — these exact people also gave me the word for what i was feeling. It could've taken longer without them. It could've been too late.
