Sgt. Ryan Sharp (right) served two tours in Iraq with the Army’s 3rd Infantry Division.

In 2008, when he returned to the States from his last tour, things weren’t the same. He had trouble thinking straight, he felt off and was deeply depressed.

Ryan and his father, Kirk Sharp (left), sat down for a StoryCorps conversation in Lincoln, Nebraska to talk about what happened when Ryan came home.
