Are you an adult? And if so are you a very young adult like 18-21? Most BPD is diagnosed in adulthood and they won't diagnose it in childhood. Emerging personality would just mean you may have some traits of BPD but are either too young, or it is too early for them to diagnose it for certain. Emerging personality isn't a DSM diagnosis like BPD but more likely a condition to verify a strong possibility of it in the future. Kind of like pre-diabetic vs a diabetic. That's my understanding of it anyway. I understand it can be very frustrating to feel so bad inside and see so many doctors and hospitals and have them be so vague with what's really going on with you. However, it's a good thing to be thorough and not just slap labels on people because that drastically effects their treatment and life. I wish you the best
