Quizplus · Accepted Answer

Lily's alternating episodes of euphoria and distress suggest that she may have bipolar disorder, which is characterized by cycling between episodes of mania (euphoria, restlessness, excitation) and episodes of depression (feelings of worthlessness, morbid thoughts, lack of energy). Major depressive disorder is characterized by persistent feelings of sadness, hopelessness, and lack of interest in activities, without the cycling between manic and depressive episodes seen in bipolar disorder. Obsessive-compulsive disorder involves intrusive and repetitive thoughts (obsessions) and/or repetitive behaviors (compulsions) that are distressing and time-consuming, but do not involve the cycling between manic and depressive episodes seen in bipolar disorder. Schizophrenia involves a range of symptoms, including delusions, hallucinations, disordered thinking, and emotional blunting, but does not involve the cycling between manic and depressive episodes seen in bipolar disorder.
