- Borderline Personality Disorder: Instability in relationships, self-image, and emotions, often leading to impulsive actions.
- Histrionic Personality Disorder: Excessive emotionality and attention-seeking behavior.
- Narcissistic Personality Disorder: Grandiosity, need for admiration, and lack of empathy for others.
3. Cluster C (Anxious or Fearful Disorders):
