Hi no one on earth,
Bpd is one of the most stigmatised mental health diagnoses.
if ur interested in it and how it develops, maybe u can read anout it or watch YouTube stuff about it?
it is also a personality disorder, one of a fair few , they are divided into 3 clusters, a, b and c.
Because of the stigma attached to bpd, I don't think it would be helpful to tell someone u think they have it,
If it helps u understand urself, or others, that's great and maybe researching it might help u...
DBT is just one of many models of therapy.
It's not my preferred choice. It's not the only choice.
Maybe another therapy will suit Ur friend, or no therapy at all.
My friend is on the spectrum I believe, but I don't feel compelled to tell him that,
I think it's best only if someone asks you Ur opinion, as it so delicate.
I Also think bpd is really hard to diagnose, it's not simple, u can't really know just by a few external factors.
And then, there are even ppl who don't believe in personality disorders at all...it's a big can of worms!
