This question bugs me to my core. PTSD, or post traumatic stress disorder, is not limited to those in the military. According to the National Institute of Mental Health, PTSD can be caused by a shocking, scary, or dangerous event that triggered a flight-or-flight response; this is meant to protect a person from harm. In chronic PTSD, which I have, the person experiences re-experiences of the trauma (flashbacks), avoidance, bad dreams, easily startled, feeling tense or on edge, feelings of guilt or blame, and frightening thoughts. Often, those with PTSD also inherit anxiety disorders.
I have PTSD due to years of sexual/physical/emotional abuse and several near death experiences. All of these triggered the fight response in me as a child and it has physically distorted areas in my brain. Childhood trauma is also very bad for the brain because it is effecting it in a more long term manner. Trauma in children has long lasting effects because the brains are still being developed and the changes that the brain undergoes at these stages are extremely important for development and personality.
Rant over. Thank you for reading.
