During a telehealth session, a 32-year-old single woman reports being home during the quarantine for a period of 4 months with no outside contact. She says she knows several people who died from COVID-19, and although she never became ill, she has become extremely nervous about leaving her house. She tried leaving her house once during the Phase 1 reopening, but she says it felt like "an elephant" was sitting on her chest and went back home. She is terrified to use public transportation or go to any stores and stand in line, in case she has another episode of chest pain and "cannot escape." She is too terrified to go out again but misses seeing her friends and family. Which diagnosis is most correct?

Choice A reason: Specific phobia involves intense fear of a particular object or situation, but the patient’s fear is generalized to multiple everyday situations, not one isolated trigger. Choice B reason: Adjustment disorder involves emotional or behavioral symptoms in response to a stressor but does not typically include intense avoidance of multiple situations with panic-like symptoms. Choice C reason: PTSD involves re-experiencing trauma, avoidance, hyperarousal, and negative mood, usually linked to a traumatic event. While COVID-19 exposure may be stressful, her symptoms are primarily avoidance-based rather than trauma re-experiencing. Choice D reason: Agoraphobia is characterized by anxiety or panic in situations where escape is difficult or help may be unavailable, such as public transportation, stores, or being outside the home. The patient’s avoidance of leaving her house and fear of “not being able to escape” aligns closely with agoraphobia.
