Most of us can relate to wanting to avoid things that make us uncomfortable – situations, people, and even work. Sometimes, we deliberately find ways to get out of confronting whatever makes us feel ill at ease. But Avoidant Personality Disorder is much more than just this. Unlike other Cluster C personality disorders that may sound more familiar, Avoidant Personality Disorder is not as well known. The National Institute of Mental Health  estimates that around 5% of adults in the USA have it. It is characterized by patterns of social inhibition, feelings of inferiority or inadequacy, and sensitivity to negative responses. And as its name indicates, individuals tend to avoid situations that trigger those emotions. Signs of Avoidant Personality Disorder  Reluctance to be involved with people unless certain they will be liked. Avoidance of activities (whether professional or personal) that would require significant contact with others due to fear of rejection or criticism.
