Does Pristiq Help To Treat Borderline Personality Disorder, Anxiety And Depression?

Hi, My wife went off Pristique, she said she didn t need to be on it anymore. My wife can have mood swings, and seems to have many traits of a personality disorder I have noticed since becoming married. Does Pristique help with BPD, anxiety and depression? Of course I cannot diagnose BPD... but wish she would seek help. Tough part is she s an MD.
