History of presenting illness (HPI): P.N, a 46-year-old male, presented to the clinic for help with his depressive mood. P.N. was referred by his primary care physician (PCP), who did a depression screening and realized that he needed a psychiatric evaluation; the PCP stated in the referral form that the patient presented to the clinic with a Solemn mood. The patient verbalized that he has been feeling sad nearly all day for the past month; he doesn’t feel any pleasure working in his food store anymore. He lacked sleep for almost six weeks. He stated that this started after the pandemic and now the price inflation. He made losses due to high prices. Last month, his store had low sales because his suppliers hiked the buying price, forcing him to increase his selling price to make a profit. During this period, all his customers avoided him since they found another food store offering lower prices for farm products. As a result, he ended up making losses instead of profits, causing him stress, frequent headaches, and weight loss due to a lack of appetite. He stated that the food store had been his dream; therefore, he had never imagined losing it. During this period, he has no drive or motivation, forcing his wife to refer him to their primary care physician. The patient denies taking any psychiatric medications; however, he takes Tylenol periodically when he has a headache.
Actual diagnosis: Major depressive disorder
F41.1 Generalized anxiety disorder
