We mean something different about the idea of "stories" when we've changed our story. We didn't get told a story. We've been living inside a story we tell ourselves. People call this a "life changing experience". I find it's the most valuable kind of learning experience I can create for others and myself.
Therapists describe this as a "change at a cosmological level of meaning". This is deeper than a change of habit, attitude or explanation. This revises the meaning of life. The "facts of life" are transformed. The world seems different somehow. Feelings have changed about oneself, others and past histories.
I find it helpful to see us living inside stories -- that we can step out of anytime. Parents put us inside their story, which early on gives us an identity and meaning to our lives. Their story usually feels too confining during adolescence and a rebellion ensues. A new story is discovered that defies the imposed parental narrative. When adults continue to live inside their parents' story, these adult-children act out anger, stifle their feelings, suffer from bad decisions and fail to find satisfaction in accomplishments. The parental story suffocates the lives that are meant to be lived.
