Individuals increasingly encounter moments in which their established identity no longer provides a viable basis for action. These threshold conditions are not defined by environmental difficulty alone, but by the sudden invalidation of the self-narrative that previously organized perception, meaning, and action. Despite their prevalence across domains, there is no unified theoretical account of how identity destabilizes and reorganizes under such conditions. This paper develops a structural theory of identity destabilization and reconstruction grounded in a cross-case analysis of 21 individuals spanning medicine, aviation, trauma, the arts, and organizational leadership. Each case was examined for rupture conditions, identity triggers, liminal dynamics, and post-threshold emergence patterns. Findings indicate that identity destabilization follows a consistent structure characterized by identity inversion, time distortion, dissociative self-observation, and collapse of a previously coherent self-narrative. Across all cases, successful reorganization depended on a recursive system of capacities that enabled destabilizing experience to be processed rather than suppressed, fragmented, or prematurely resolved. This process, identity metabolization, determines whether rupture leads to reorganization or to non-transformative outcomes. Critically, outcomes diverge not because of differences in rupture severity or prior competence, but because of differences in metabolization capacity. The resulting Identity Metabolization Model reframes transformation as a capacity-dependent process of metabolizing disruption and introduces identity rupture as a new unit of analysis. It offers a framework for understanding how individuals and leaders maintain or lose coherence under conditions where identity stability can no longer be assumed.
