Depression in the Primary Care Setting.

A 45-year-old woman with hypothyroidism that has been treated with a stable dose of levothyroxine presents to her primary care provider with depressed mood, negative feelings about herself, poor sleep, low appetite, poor concentration, and lack of energy. These symptoms began several months ago during a conflict with her partner. Although she has been able to continue with work and life responsibilities, she feels sadness most days and occasionally thinks that she would be better off dead. How would you evaluate and treat this patient?
