Avoidant personality disorder is a personality disorder characterized by a pervasive pattern of social inhibition, feelings of inadequacy, and hypersensitivity to criticism or rejection. Individuals with this disorder often avoid social interactions or situations that may lead to criticism or rejection, as they have an intense fear of being negatively evaluated by others. They may have low self-esteem and tend to isolate themselves to protect themselves from potential rejection. This disorder can significantly impact an individual’s ability to form and maintain relationships, as well as their overall quality of life.
