Trusting Fight Or Flight

I often find myself wondering if because of my PTSD, when I am in grave danger in the future, is my fight or flight response going to work properly? Am I going to Freeze when I should have fought, or fought when I should have run? I mean PTSD affects this very primitive mechanism in our brains, so is it unreasonable to believe that it might malfunction when we need it most? PTSD does affect this mechanism, it affects it but doesnt damage it. Feeling Helpless is your fight or flight system... Trusting Fight Or Flight
