What I always do when I am trying to break a trigger is do self talk before, during and after the trigger. I keep telling myself that that was then and this is now and that I need to focus on this moment and what is different about it. You can change those messages and triggers. And of course in therapy you need to diffuse those triggers too by talking about the incidents in therapy in detail and with your feelings involved. Good insight Googley, that you noticed this trigger! Very good work!!!!
