Michael Carroll served 18 months in Iraq for the United States Army. After coming home in 2004, doctors found that he suffered from Post Traumatic Stress Disorder (PTSD).
Mental health experts say the disorder develops in some people who have experienced a shocking or dangerous event. Such persons may feel frightened even when they are not in danger. They also can suffer from depression for months or even years after the event.
Michael Carroll left the army after receiving an honorable discharge. He described the change to civilian life as difficult, and that he was quick to express anger.
