You have had this experience.  I have had this experience.  We suddenly react in an unusual way to a stressful or difficult situation or relationship.  Maybe we get surprisingly angry or suddenly extremely anxious and fearful, and words come out of our mouths as if controlled by some other source.  And we say to ourselves, “Where did that come from?” 

Pete couldn’t sleep.  Instead he would lay in bed and worry about seemingly everything.  Sometimes his worry related more to the price of hogs and the lack of rain.  At other times he worried about his children and how they would find their way in this world.  In all cases the worry felt overwhelming and debilitating.
