This is very at describing PTSD, especially for people who want and we sure hope you want, to better understand what PTSD is and how it affects those that have it. No matter if it is a family member or a friend, the more aware that you are of this illness, the better you can help and understand your loved one. It is written in lay man terms. Dr. Pam Hall knows her stuff and her goal is to make people aware of this illness so that life can be better lived by all of us, Veteran and Civilian alike.
