Many DID people have a dual diagnosis with BPD, or were misdiagnosed as BPD.
We were misdiagnosed in the past (I am like the opposite of BPD - we even got kicked out of DBT for not being impulsive/for doing as we were told!), although niva might fit it (her personality is stable, and she doesn't have dramatic relationships, but she's very intense, has abandonment issues, used to harm the body, and of course is prone to dissociation under stress..)
What about you/your system?
