The biggest thing is that even doctors don't know a lot about PTSD. Families sometimes get upset because someone goes off the deep end once too often and they just don't know why. It isn't for them to know why, it is the way the person reacts to a situation. As in Sam's case, try being in the field and watch all the guys in your group die as you survive even though you are wounded. Yes, it is very humbling and very emotional that they can't allow to happen. I thank God that we have men like Sam and many others who do the job and survive. For the others, I just pray that they are looking down and saying they did what they needed to do. Thanks, everyone.
