A great question asked in "Adult Children of Alcohlics" 12 step program is -
WHO AM I WITHOUT TRAUMA?
My sponsor and I added to this:
Who am I without envy?
Who am I without anger?
Who am I without jealousy?
Who am I without fear?
Who am I without self pity?
Who am I?
Without all those negative feelings, I am free to choose who I want to be.
It's a heroes journey, and you are the hero.
