Borderline Personality Disorder
Does someone you know and possibly love have very erratic mood swings?
Does he or she agree to something one day and the next day says something completely different?
Does that person love you one day and hate you the next, with hardly any detectable transition?
Does that person hate to be alone and feel abandoned or rejected over the tiniest issues?
Is she highly sensitive, to the point where you learn to stifle your spontaneous speech as a way to prevent an outburst?
That person may be suffering from Borderline Personality Disorder.
About 10% of the adult population is estimated to suffer from Borderline Personality Disorder.
