Mary's sudden change in mood, feeling like she had a great idea and then feeling down, could be indicative of bipolar disorder, which is characterized by episodes of both high (mania/hypomania) and low (depression) mood. Additionally, quitting her job impulsively could also be a sign of a manic episode.
