Both borderline personality disorder and bipolar disorder involve impulsivity and unstable emotional experiences and mood. People with borderline personality disorder, however, also have problems in self-image and relationships. Specifically, individuals with borderline personality disorder have identity disturbances, such as an unstable sense of self and chronic feelings of emptiness. They also have relationships in which they alternate between extremes of seeing someone as good/worthy and seeing them as bad/worthless. They experience intense fears of abandonment by others on whom they feel dependent. Typically, the signs of borderline personality disorder are evident over at least several years (although they appear to wax and wane over time), while the signs and symptoms of bipolar disorder appear in episodes.
