Today is #PTSD Awareness Day. It's not only veterans who suffer from it, but regular people and journalists. For me, it started in Iraq after I covered a multiple suicide bombing. As the death and destruction piled up over the months, it got harder to function outside a war zone I only felt normal when I was surrounded by chaos. I would have panic attacks when out in a normal city. Eventually I got help and after that I was very careful when covering conflict to look at my mental health and those of my colleagues.
