'A war within myself': One veteran's struggle for life after combat

“The rest of the morning was spent picking up body parts, still warm, in perfect condition, like they had just fallen off the owner. My Marines were crying and I yelled at them, calling them demeaning names and to man up. This day caused so many feelings & emotions in me that I wrote my dad about the event and how much it was tearing me apart. We never talked about it, but one year later, he died and I found it in a safe under his bed. Nothing else was in the safe. He took it to the grave. I felt so guilty and ashamed that I told him. I thought that I caused the stress that led to his fatal heart attack.”
