This 2018 publication is a compact easy-to-read book about PTSD that's a good choice for adults also who have teens and need an introduction to the topic. It includes useful information on coping with anger, anxiety, nightmares, and depression. My own experience of being bullied in the workplace at St. Alphonsus Regional Medical Center for nearly three years, and dealing with PTSD as a result is primarily responsible for my intetest in this topic. The only problem with this book, published by Instant Help Books, is that on some pages, the print for no obvious reason, was much lighter than on adjacent pages. But all the information was there. This title is part of the New Harbinger Instant Help Books series for teens.
