Here's a defintion
Mental disorder
Any clinically significant behavioral or psychological syndrome characterized by distressing symptoms, significant impairment of functioning, or significantly increased risk of death, pain, or other disability. Mental disorders are assumed to result from some behavioral, psychological, or biological dysfunction in the individual. The concept does not include deviant behavior, disturbances that are essentially conflicts between the individual and society, or expected and culturally sanctioned responses to particular events.

And only you can lead them to salvation \o/ Praise be the lord! Praise be Josuke!
