The brain crazy making gets me too! Most days I can just sluff it off, but there are times when it lasts a few days until finally I pop! Usually though, I hate being impulsive, so I try to talk about what's bothering me instead. (I end up coming across like I dont care, but years of impulsive over-reaction taught me to calm down first) Even though my ex is an A, and even though he is an ex, he was always so understanding of my nonsense. Most of my thinking messes have been unprovoked :-P
