Based upon what I have read and been told by professionals.........In PTSD and other disorders......lack of emotion.......is a safety mechanism that distances yourself from the traumatic event(s).....a way of detaching from it. No memories......same thing basically.....you brain is protecting you.......protective mechanism.

After a recent trauma of mine..........I lost a whole month and didnt release it had gone by. And then a flood of flash backs..........etc. Very overwhelming.
