Cure For Borderline Personality Disorder

Is there a cure for Borderline Personality Disorder? (BPD) How can you evaluate online information that promises to tell you about a cure if you buy a product or a certain book about a cure? Can you trust pitches that claim to tell you that they can cure BPD? Are they sales pitches or reality? Can loved ones of those with BPD trust pitches that promise to help them save relationships by purchasing information that advertises the cure for BPD or claims that someone has “solved” BPD in some nice neat across-the-board way?
