Looking - welcome to the club. Unfortunately, the whole mental health system is skewed against us and against our kids. Especially the "youth" level. They somehow don't want to see the real problems because they don't want these "poor" kids ending up with "labels".
On top of that, if it is indeed a personality disorder, these are extremely difficult to treat. Not impossible. But the patient has to see the need to change and be willing to put in a huge effort over a few years. It isn't easy.
