A 27-year-old woman presents to the emergency department with chest pain. She recently returned from a vacation to Taiwan with her boyfriend, which she states went poorly. He left her after the trip. They had stayed in local hostels, and she noticed several individuals who appeared ill. She states the chest pain she has is worse with deep breaths and started when her boyfriend left her. The patient has a history of obesity, depression, anxiety, and several sexually transmitted infections. Her temperature is 97.0°F (36.1°C), blood pressure is 119/70 mmHg, pulse is 108/min, respirations are 22/min, and oxygen saturation is 95%. Cardiopulmonary exam is unremarkable. There are multiple healed scars over the patient's wrists bilaterally. During the physical exam, the patient begins hyperventilating and crying. She is given lorazepam and subsequently feels slightly calmer. An initial ECG is notable for sinus tachycardia, and a chest radiograph is performed as seen in Figure A. An initial troponin is 0.6 ng/mL (normal = 0.4 ng/mL). The patient subsequently complains of chest pain and shortness of breath again when one of the technicians enters the room who reminds her of her boyfriend. Which of the following is appropriate treatment for this patient's chief complaint?
