How do you know if you are bipolar personality?

Not sure: Some people have certain characteristics about themselves which they believe are just part of their personality, when in fact, the person has a problem with their mood called bipolar disorder. A board certified psychiatrist or psychologist can perform an evaluation and tell you what you have and what can be done about it, if you want to do anything about it. Start with a proper diagnosis.

Agree w Dr. Passer: In actuality there is not a condition called Bipolar Personality Disorder.
