Let's say we start with what they call a "problem saturated narrative" that includes stuff like "no one understands me," "I'm afraid of rejection," "I'm not lovable," and "I'm never going to find anyone." So that narrative strings together all the events that prove that this is true regardless of context or accuracy.

To make an alternative and preferred narrative, you start by "deconstructing" the problem narrative with lots of questions. Like, "was there ever a time when someone did understand and accept you? who was that person? how did it feel to have that person respond to you that way? what would it be like if that person had be a major figure in your life? how would you be different? what in particular would you do differently? etc. And challenge each thing until a whole set of exceptions and possibilities emerge. Then shape that and strengthen it and that becomes the alternative narrative. Does that help?
