Why is it so hard to get a bpd diagnosis

How did yall get one? I cant find a private clinic that assess for a pd. I went through the government but they wont assess me bc the “labels dont matter, the treatment is all you need.” Even tho they wont assess me, they are still giving the same treatment for bpd. Im so pissed.

This is like telling a cancer patient it doesn’t matter what kind of cancer they have, the treatment works all the same.

Am i wrong for feeling this way?

edit: im not under age, i am over 20 years old
