I was on my hands and knees on my living room floor, uncontrollably shaking to my bones and sobbing. I felt terror and hopelessness but mostly I felt so alone in this world. It was suddenly dark outside and I noticed that I have been crying for nine straight hours. I paused and wondered if that was a normal reaction, what is normal in a situation like this? Was this my PTSD, is a past trauma being triggered by the sound of violence and rage?
