The correct answer is bipolar disorder.

Bipolar disorder, also called manic depression, is a mental health condition that causes extreme mood swings and behavioral changes.

The disorder is characterized by two phases: the emotional heights (mania) and the emotional laws (depression).

During the emotional heights, a person has increased energy, is optimistic and very active. The person has an exaggerated sense of self-confidence and  experiences extreme well being.
