I find it amusingly ironic that me the relatively stable 26 year old is classified as BPD but me the 16 year old with two major suicide attempts in under a year, self harm, bulimia and paranoia was a tentative maybe.
But that's how it works. Many BPD behaviors can be attributed to simply being a teenager while others require a pattern that needs time to establish itself.
I'm sure you'll get your answers soon enough and good luck.
