According to PTSD United, 20% of adults in the United States who have experienced a traumatic event suffer from PTSD. The statistics alone are staggering, but can only tell a portion of the story. The trauma and anxiety associated with PTSD is a constant burden, inseparable from the sufferer. It was once a condition that was attributed only to returning combat veterans, but more and more the condition is diagnosed in those who have experienced violent crime or lived through catastrophic events.
