I've also heard comments like that for my whole life, either people who tell you how 'special and unique' you are, or those that say that you're bad tempered and bratty... I once heard someone say that the connection with a borderline person is unlike any other friends they had, that at times it functions on some special level of understanding that goes beyond what 'common' people can see and experience, and sometimes the connection gets broken off completely.
I think even if on an emotional level we all might function according to similar patterns, intellectually the issues we deal with make us more aware and give us insights into the sides of life and interpersonal contact that might never even occur to others.
It's a struggle and there's no doubt about that but what I can at least to some extent appreciate about the whole situation is that I had to dig deep to understand why I am like that and why other people are the way they are, and it made me think.
BDP doesn't have to define us!
