Final answer:
Cordelia, an active duty marine who exhibits symptoms such as jumpiness, irritability, avoidance of trauma-related discussion, and flashbacks, is likely experiencing Post-Traumatic Stress Disorder (PTSD), which is a response to severe psychological trauma.
Step-by-step explanation:
Cordelia, an active duty marine who served in Afghanistan, is described as being jumpy, irritable, avoiding discussions about a traumatic event, and experiencing flashbacks. This content loaded scenario suggests that Cordelia is likely suffering from Post-Traumatic Stress Disorder (PTSD), which is an anxiety disorder that can occur following the experience of a traumatic event. PTSD was common among military personnel, such as American GIs during the Vietnam War, with symptoms including flashbacks, irritability, and an aversion to reminders of the trauma. The term 'disorder' can be contentious as some argue that these reactions are normal aftershocks of severe psychological trauma.
It's important to understand that PTSD is a serious condition that requires medical and therapeutic intervention. Early diagnoses were often missed or misunderstood, and this lack of timely treatment resulted in long-lasting effects on veterans' mental health. Treatment for PTSD often involves a combination of therapy and, in some cases, medication to help manage the symptoms.Given Cordelia's symptoms of being 'jumpy', irritable, avoiding talks about her late friend, and experiencing flashbacks, it is consistent with the acknowledged symptoms of PTSD that have affected many veterans historically and continue to impact those who have experienced severe psychological trauma.
