It's our vulnerabilities that gets exposed when things don't go the way we want them to resulting in certain dysfunctions like automatic negative thoughts, emotional lability, feelings of emptiness, fear of abandonment leading to interpersonal issues and in some cases certain behavioural issues like impulsivity, anger issues, self harm etc. This in some people can get reinforced and form a pattern which is usually referred to as personality disorder. It's just a name given to certain patterns of thinking, feeling and behavior leading to some dysfunctions at times.
