What is the difference between bipolar type 2 vs borderline personality disorder?

Mood swing duration: The two conditions have a lot of overlap although the more important distinctions are that bipolar disorder type two would imply that the patient will have changes in mood that would last weeks including either hypomania or depressed mood as opposed to changes in mood in the same day. Additionally, patients with borderline personality disorder are excessively reactive to closeness or abandonment.

Borderline: Intense fear of abandonment, being manipulative, impulsivity, a tendency to think of people and things in all good or all bad terms, self mutilating behaviors, drug and alcohol abuse, sexual impulsivity, a profoundly disturb sense of self, and extreme emotional volatility. Bipolar disorder is characterized by extreme mood swings from deep depression to hypomania, or to the stratosphere of mania.
