Explanation:

Borderline Personality Disorder is a health problem involving the areas of psychology and psychiatry, very difficult to diagnose. People who have this type of disorder impulsively switch attitudes, may have outbreaks of hatred and, in extreme cases, even attempt suici**. In other words, people with this disorder alternate between extremes of flattery (when their needs are met) and aversion (when they feel neglected).

A feature that is often very common in borderline is the fear of abandonment or intense discomfort just thinking about being alone. The problem is that the way a borderline patient expresses this discomfort of abandonment and loneliness can be aggressive, overly intense, and a little messy.
