i understand where you are at in trying to understand why you are reacting to a trigger, or trying to figure out why you were triggered and such. i used to drive myself up a wall doing that. i would really bash myself for spinning out of control for "seemingly no reason". then i developed a mantra that made me feel better and allowed me to let go. understanding that i am mentally ill and having ptsd and that i do get triggered by things i dont understand and i am going to react certain ways and not know why, it is JUST THE WAY I AM WIRED. when i get in these spots i now tell myself that this is NORMAL FOR ME. because it is a totally normal reaction for the way i am wired. so now i dont have to stress about it, which only makes it worse. i can just let it go, which makes it better and lessens the anxiety. hope this helps. take care.
