There are 10 main types of personality disorders: paranoid, schizoid, schizotypal, antisocial, borderline, histrionic, narcissistic, avoidant, dependent, obsessive-compulsive. Personality disorders all have in common behaviors that make it very hard for the individual to get along with others at home, at work, at school, and in personal relationships.  The behaviors are difficult to change, happen over and over, and often started when the individual was a teenager or young adult. These individuals often are not aware of their behaviors and become angry or sad when told of them by others.  Treatment helps the individual improve their quality of life and relationships. 
           
Paranoid Personality Disorder: The individual is very fearful of others, that others are out to do them harm, persistently holds grudges and is unforgiving of insults, and is recurrently suspicious. 
     
Schizoid Personality Disorder: The individual does not have social relationships, has limited expression of emotions when in the company of others, does not want or enjoy relationships (even with family), and almost always prefers doing things alone.
  
Schizotypal Personality Disorder: The individual has extreme discomfort with close relationships, has odd beliefs (supernatural), has odd ways of talking, acting, and dressing, has few friends or relationships outside close family, and has excessive social anxiety even with people with whom he or she is familiar.
        
Antisocial Personality Disorder: The individual repeatedly does things resulting in arrests, is deceitful, does not plan ahead or see consequences, recklessly disregards own safety and the safety of others, consistently fails to honor responsibilities, cannot keep a job, and does not feel guilt or remorse for things done.
         
Borderline Personality Disorder: The individual frantically fears and avoids abandonment (real or unreal), has intense relationships that do not last, sees others in a black and white way: either others are all good or all bad, has extremely unstable self image, is impulsive (sex, spending, substance abuse, reckless driving, binge eating), almost always feels empty on the inside, and cannot control anger.
              
Histrionic Personality Disorder: The individual needs to be the center of attention, is often sexually provocative with others, has rapidly shifting shallow exaggerated emotional expressions, uses his or her physical appearance to get attention, is easily influenced by others, and believes his or her relationships are closer than they are actually.
              
Narcissistic Personality Disorder: The individual has an extremely exaggerated view of his or her importance to others, of his or her abilities, believes that he or she is so exceptional that he or she can only interact with other exceptional people, is arrogant and envious of others, and takes advantage of others to get what he or she wants.
          
Avoidant Personality Disorder: The individual almost always feels disapproval, criticism, or rejection by others, interacts with others only if certain of being liked, has extreme fear of being shamed or ridiculed, avoids social interactions because of feelings of inadequacy, and avoids taking risks in personal relationships for fear of embarrassment.
 
                
Dependent Personality Disorder: The individual needs frequent reassurance and advice from others to make every day decisions, avoids expressing disagreement with others for fear of losing support or other's approval, feels uncomfortable or helpless when alone, feels exaggerated fear of being unable to care for self, and urgently seeks another relationship when one ends.
 
             
Obsessive-Compulsive Personality Disorder: The individual is preoccupied with details, rules, lists, orderliness, organization, or schedules to the point that the task originally attempted is forgotten and not completed. He or she is excessively devoted to work to the exclusion of leisure activities, is inflexible on morals, ethics, and values, and is very rigid or stubborn.
