Veteran battles Seasonal Affective Disorder

  As the days grow shorter and darkness comes earlier, thousands across the country experience seasonal affective disorder, or SAD. For many veterans, like U.S. Marine Corps disabled veteran Tobias Williamson, this condition can be especially difficult. "My son, my wife, our family, this house. All of that depends on where I'm at with myself," Williamson said, highlighting how his mental state affects every aspect of his life.
