Borderline Personality Disorder is characterized by a pattern of instability in interpersonal relationships, self-image and affections, with marked impulsivity that appears in various contexts.

These are the behavioral patterns associated with people who have this disorder. At least five (5) of the criteria used for diagnosis by DSM5 must be present:

1. Desperate efforts to avoid real or imagined abandonment;

2. A pattern of unstable and intense interpersonal relationships characterized by alternating between extremes of idealization and devaluation;

3. Identity disturbance: marked and persistent instability of self-image or self-perception;

4. Impulsivity in at least two self-destructive areas (for example: spending, sex, substance abuse, binge eating and others);

5. Recurrence of suicidal behavior, gestures or threats or self-mutilating behavior;

6. Affective instability due to marked mood reactivity (irritability or intense anxiety lasting generally a few hours and rarely more than a few days);

7. Chronic feelings of emptiness;

8. Intense and inappropriate anger or difficulty controlling it;

9. Transient paranoid ideation associated with stress or intense dissociative symptoms.
 
If you identify with any of these behaviors (or know someone who exhibits them), seek out a mental health professional to make an appropriate and accurate diagnosis.
