    ** Please use caution when reading any of the disorders listed above.
    Do not panic because you find a couple of symptoms that match a specific personality disorder.
    We all have symptoms that can apply to one or another disorder
    but what makes it a disorder is a "pervasive pattern"
    and that is how the psychiatrists and psychologists
    determine if it is a specific disorder.**
