I'm finally accepted that I might have developed a tic. I don't know for certain. I was sexually abused through out my childhood and only the past 2 years since ongoing nightmare reliving it that it developed into a constant thing. I find myself keep twitching my head. Moving my head rapidly to 1 side. sometimes from 1 side to the other in same way I did during the abuse when I struggled. It only happens when ptsd symptoms flare up and feel panicky scared.
