Jerome, a 35-year-old welder, presents with persistent fatigue and lack of energy over the past six weeks. He has a history of anxiety and depression, previously treated with sertraline, which he discontinued after six months due to improvement. He now drinks three bottles of beer nightly, a significant increase from his previous consumption twice a week. He reports disrupted sleep patterns and stress related to his job. His physical examination is normal, but he appears sad and apathetic.
