Case

A 41-year-old paramedic was assaulted at work four months ago. They report intrusive images, nightmares, avoidance of the location, persistent guilt, irritability, hypervigilance, and exaggerated startle. Symptoms are impairing and have persisted beyond one month. They also feel detached from family and have lost interest in activities; the assault involved a credible threat to life.
