I myself am a war veteran (viet nam), and I know the feelings of lost buddies, the way people look at you, and think of you, why does he react a certain way. Post Traumatic Syndrome is a serious thing to push people away from you, believe me....its a serious life changer, my wife can attest to that. I don't ask for sympathy but just understanding..the war for was 43 years ago....the ghosts don't go away....!!
