A 36-year-old woman of Chinese descent presents to the PMHNP after a referral from her primary care physician, who has worked up her physical complaints. These physical complaints include headaches, dizziness, and abdominal pain. The patient says she also experiences insomnia, difficulty concentrating, anxiety, and fatigue. These symptoms started approximately 6 months ago, after her husband had an affair, which he ended. She is also under stress at work, since she just received a promotion. Which culture-bound syndrome should the PMHNP include in the differential diagnosis?
