Whether you’re sociable, reserved, funny or forthright, everyone who knows you would likely list the same traits when describing your personality. These characteristics are the combined product of your heredity and early life experience, and they are fixed by the time you reach adulthood.
People with personality disorders have traits that cause them to feel and behave in socially distressing ways, which often limit their ability to function in relationships and at work. Depending on the disorder, their personalities are generally described in more-negative terms: dramatic, clingy, antisocial or obsessive. As many as 15% of U.S. adults have one or more personality disorders.
Among the 10 conditions that are considered personality disorders, some have very little in common. Doctors typically group the personality disorders that have shared characteristics into one of three clusters:
Cluster C ~ personality disorders are characterized by anxious, fearful behavior and include obsessive-compulsive, avoidant and dependent personality disorders.
There’s no cure for these conditions, but therapy and medication can help. The symptoms of some personality disorders also may improve with age.
~~~ For me, based on this information, it would be difficult to really pin-point my cluster. Maybe my pdoc’s opinion and assessment are different as he has never shared this with me.

Thanks to a commenter who wished clearer info on clusters, I found this site offering much better info:
