Welcome to the site.
I am a Psychiatrist and i believe i can help you with your query.
Well, NO, a person with Bipolar 2 disorder will not have either histrionic traits or borderline traits in his personality as these type of personality disorders are straight away excluded as a diagnostic possibility once your diagnosis is confirmed of Bipolar 2 disorder. In other words only 1 diagnosis can be made , either bipolar disorder or histrionic-borderline personality disorder, they cannot co-exist since they are mutually exclusive of each other.
Now in order to be more accurate about your diagnosis, please tell me that whether you have absolutely NORMAL periods in between your 'low phase' or depression and 'high phase' or hypomania ?
I will get back to you to complete my answer once you answer my query.
