A 30-year-old woman presents to your office for the evaluation of fatigue. For the past 2 months she has felt run down. She says that she doesn’t feel like participating in activities that she previously enjoyed, such as her weekly softball games. She has not been sleeping well and has not had much of an appetite. On questioning, she admits to feeling “down in the dumps” most of the time and has found herself crying frequently. She has never gone through anything like this before. She denies any thoughts of wanting to hurt herself or anyone else. Other than becoming tearful during her interview, her physical examination is normal. Her blood tests, including a complete blood count and thyroid function, are normal. A serum pregnancy test is negative. You diagnose her as having a major depression and, along with referring her for counseling, start her on fluoxetine.
