This document discusses mental disorders and their treatment. It begins by describing behaviors that seem unusual like checking a bag frequently or having increased anxiety before an exam, and notes that these could be signs of mental disorders. Mental disorders develop gradually due to factors like heredity, personality, stress tolerance, childhood experiences, and an inability to cope with stressors. The document then discusses the nature of stress and conflicts/frustrations as sources of disturbed mental health. It provides examples of different types of stressors, conflicts, and frustrations people may experience. Finally, it notes that people generally use problem-focused or emotion-focused coping strategies to deal with stressors, but that sometimes leads to mental disorders if coping is ineffective.
