Perhaps you would never know what really happened, perhaps things would get clearer would time, but that is immaterial. The important thing is to release whatever is coming thru your memory, release it, as it is just your past, not you! Make yourself, your present, your future more important than your past, IT IS.
I remember when as a child you get hurt, and run up to your parent, they wouldn't counsel you, or anything, they would just hug you and say: ITS OK, ITS OVER, ITS OK, ITS OVER.
That is what you have to say to that screaming child in you, EVERY DAY. Walk up to him and embrace him with your love, let him know you are there for him. Listen.
