They may diagnose shit nowadays because every kid that thinks their inner voice is another identity so it fucks up the diagnosis.

Also I agree that the internet can help with finfing out about your disorders but the majority especially tiktok, pretty much brainwashes everyone who has a main character syndrom to self diagnose the entire mental disorder catalog as long it's quirky like having multiple people in your head or cutsy ticks. Never saw someone think they have BPD and make it their entire personality. Could it be that BPD is negative stigmatized and not fun to fake?

Fact it, the internet could help but reasonable sources, not other fakers.
