I'm so sorry to hear Evie's having a bad time with flashbacks. I hope she can get to the neuropsychiatrist quickly. When I have flashbacks and dissociation, I am sometimes vaguely aware that I also do not move or respond to much, if any, external stimuli. I had two new flashbacks this past week and don't really know what they're about. So I now know that new ones can come at any time. I will try to see if I can discern any warning signs in myself.
