Mental illnesses are stigmatized in the world at large; BPD is often stigmatized in the mental health world. As a therapist, I’ve worked in many agencies and clinics where staff has been exasperated by clients’ “attention seeking” behavior, and characterize them as manipulative. Many feel that efforts are futile, as personality disorders are more ingrained, and often present with more resistance to treatment. Though I think having loving and good supports, insight, and the right treatment are huge advantages to a better prognosis.
As someone else mentioned, BPD often overlaps with other diagnoses’ symptoms, as mood swings and impulsivity can look like Bipolar and anxiety disorders. BPD is not characterized by episodes of “mania”, though regular behavior can resemble it. And I’ve personally never associated lack of compassion with BPD, though I can see how the manipulation can convey them as self-centered. I don’t really like the term manipulation, as it makes it seem like the person is some diabolical puppet master, when I think they usually act in whatever way gets the response they are seeking, because they don’t know how to get it in a healthy way.
