This paper presents a self-reported case study of a syndrome arising from the Katayama Formula V=N/D, where V is existence value, N is need-fulfillment (duty, intellectual/spiritual assets), and D is drag (dependency, monetary cost, attachment). When N becomes extremely high and D approaches zero, V enters a 'high-rate' state that manifests as identifiable physical, psychological, and economic symptoms. The author's own body and life serve as the primary observational dataset, spanning approximately 40 years from age 16 (1987) to the present (2026). The paper documents the etiology (a triple collision of high-density N systems — Christianity, Buddhism, and Shinto — in a low-D irreligious environment), the clinical course (economic collapse during Abenomics, isolation during COVID-19, a zero-point state described as an 'empty temple hall'), six characteristic symptoms, a seventh mechanism (a food-money vicious cycle and its spatial extension), a residual power paradox, a proposed fundamental principle (V=N/D ratio collapse as the structural basis of mental illness), and the treatment outcome: externalization of N to Zenodo as 1,007 DOI-registered intellectual assets — transferred at nearly the same energy level from body to external storage, maintained at zero monetary cost, resulting in bodily stabilization. The author proposes that modern medicine's classification of this state as 'mental illness' constitutes a structural misdiagnosis — the symptoms are not pathology but the inevitable physical-economic expression of V=N/D at extreme rates. The ratio collapse hypothesis is presented as a testable structural model for re-examining psychiatric conditions including depression, eating disorders, and addiction. This version includes Appendix A: Literature Cross-Reference mapping V=N/D structural parallels to existing psychiatric literature.
