not really. from my experience, the people who 'casually self diagnose' are such an inconsequentially small minority that really only exist on twitter, so I dont care all that much. however, if you interact with these types of people a lot I can understand how it wears on you.

the only time it has ever bothered me is when one of my friends was going through a rough patch and would try and hit me up for some of my meds saying he thinks he has adhd n shit, and I knew this dude made well over enough money to afford a psychiatrist
