A diagnosis of bipolar is often a misdiagnosis for borderline personality disorder, which is like unmedicated bipolar on steroids. Look up borderline personality disorder in your search engine. Read. See if it resonates more thsn just bipolar. It is harder to treat borderline (requires patient compliance and a tremendous amount of serious therapy, usually dialectal behavioral therapy). Unlike bipolar, medications dont completely stabilize borderline moods and nasty behaviors. They remain nasty and manipulative and very unstable. Often bipolar and borderline coexist. You can not reason with a borderline. They can have a few good days or even act nice for a few months, but it never lasts. Deep therapy, an extreme willingness and desire to change and very hard work by the patient is the only known treatment. Please stop rescuing her. She will never get help if you are there to scrape her off the ground. It sounds as if you are realizing this. Lots of love and light!! Be nice to YOU today.
