WE ARE ONLY AS SICK AS OUR SECRETS. Our brain keeps secrets from us to protect us. This causes mental and physical problems. You can get around this natural defense by writing about the things and people that have hurt you.
Write down the bad things that happened to you and how they honestly made you feel. End each thing with how you now look at it. You must use things like, I now understand, I now realize, I now appreciate, or I now know. Your brain then rewires itself, sets you free to win. Destroy what you write and never tell anyone.
