well #1 unless things have changed since i was ~in the system any teenager telling you they’re diagnosed borderline is almost certainly lying. its uncommon to be diagnosed with a personality disorder as a minor in general unless its extreme, and even then, usually you’ll be diagnosed PDNOS. this is based on personal experience tho so dont take it as gospel
as far as the rest of it goes, i think theres been a significant uptick in self diagnosis, and consequently, people walking into a psych office with a particular diagnosis in mind already. so both i guess
