No it doesn't. It shows they have a high and mighty attitude and they're fucking ignorant. They can keep their lack of medical expertise to themselves.
Yep. I have ADHD and I'd never subject someone else to the cooking video I forgot about, with the tutorial I'm watching, with the Spotify playlist I forgot was on, while the menu track plays on the game I was about to play.
This would be torture for any other human. Even if I, with my ADHD, walked into a room that sounded just like what I just described, I'd be incredibly unable to concentrate. I can only tune out a cacophony of my own doing.
Also, OP, I have misophonia, and this is not that. You are rightfully unable to handle this level of noise. Misophonia is more an intolerance to certain specific sounds. Like I'm 100% peaceful but random kissing noises and smacking make me imagine driving a dagger into someone's chest. That sort of thing.
If I didn't have a small lake to go to and cry on my lunch breaks, I think I'd have completely broken and quit my job while screaming at everyone around me to fucking do something.
Thank God I can just stare at some birds and water and remember what life is.
Instead of simply accepting that one might be attracted to a spectrum of different kinds of people, they immediately feel internal guilt, directed outwards as hatred, because it might give them some sort of label they've been trained to despise.
