Bipolar disorder: Making the Dx, selecting the right Rx.

A 23-year-old woman seeks medical attention at the request of her boyfriend because she's been "miserable" for 3 weeks. In the examination room, she slouches in the chair and says her mood is low, her grades have dropped, and she no longer enjoys social gatherings or her other usual activities. She has no thoughts of suicide, no weight loss, and no somatic symptoms.
