Personality disorder, not otherwise specified, means you don't fit any other DSM personality disorder classifications as applied by a psychiatrist. One can't really diagnose one's self as there are things one can't see when looking at one's own behavior. I'm not a doctor either but from the list you gave you seem to fit Borderline personality disorder.

If you fit one or another of the disorders, you might have that disorder AND another but not "not otherwise specified". That diagnoses is only for those that don't fit anything else, not for if you have one and others in addition. There are 10 personality disorders, "not otherwise specified" is not something you want as it has no clear way to work on it, it's just what's left over if you don't fit any of 10; it's not a "little of this, little of that" but a "not much of the above".
