In Step 1 you recognized that the compulsion to engage in the addictive behaviour does not express a real need or anything that “must” happen; it’s only a belief. In Step 2 you state very clearly where that urge originated: in neurological circuits that were programmed into your brain long ago, when you were a child. It represents a dopamine or endorphin “hunger” on the part of brain systems that, early in your life, lacked the necessary conditions for their full development. It also represents emotional needs that went unsatisfied.
