Nаte is а 28-yeаr-оld married male. He has a very demanding, high-stress jоb as a secоnd-year medical resident in a large hospital. Nate graduated with top honors in both college and medical school. He has very high standards and can be very self-critical when he cannot live up to his expectations. Lately, he has struggled with significant feelings of worthlessness and shame because of his inability to perform as well as he always has in the past. For the past four weeks, Nate has felt unusually fatigued and finds it increasingly difficult to concentrate at work.

He reports shifts in mood between “feeling great” and “feeling like my life is over.” He denied any suicidal ideation and denied the use of drugs and alcohol. When asked how long he has experienced these mood swings, Mr. S. said, “Wow, since I was 17 or 18. I have around 10-15 mood swings a year. They are not really that bad, though.
