All war belongs on paper - here's how to go to battle: You write down each and every stressful thought, and then ask yourself four questions about it.
Is it true?
(don't know for usre, sure feels that way)
Can I absolutely know it's true?
(not at present, maybe never)
How do I react when I believe this thought?
(pain and anger and resentment and fear. eww.)
Who would I be without the thought?
(fun, creative, joyful)
Afterward, when you have completely wrestled the thought to the ground, you replace it with a "turnaround"—an opposite thought, one that is "as true or truer" and that doesn't cause you suffering.
