I think one of the main reasons personality disorders are so tricky is because there is so much overlap between the disorders. I go with ASPD for myself because that's the closest thing, but the label isn't something I lose sleep over though I do read about it when I want to, I read about NPD and BPD as well. Personality disorders, especially NPD and ASPD, run in my family but I strongly suspect my younger sister has BPD or at least strong traits from what I know about that disorder.
