A personality disorder is not just an unusual personality. It's when your personality traits cause significant problems in your life or keep you from relating normally to others.

People with schizoid personality disorder are:

  • Emotionally detached and prefer being by themselves rather than with other people

People with schizoid personality disorder often:

  • Don't have or want close relationships with others—they prefer to be alone

  • Aren't interested in physical contact and sex—they often don't date or marry

  • Don't seem to care what other people think of them

  • Have problems expressing anger

  • Choose jobs and hobbies that don't require interacting with people

They may have depression and other personality disorders in addition to schizoid personality disorder.
