Objective: Based on an extreme case of comprehensive mental system collapse and complete self-healing without any professional external intervention, this study constructs the MFY Three-Variable Steady-State Model, which can simultaneously explain daily psychological exhaustion, interpersonal defense dilemmas, and clinical psychopathological phenomena. The model reveals the endogenous self-organizational repair laws of the mental system, providing a natively generated, testable solution for operationalizing the self-actualization path in humanistic psychology. Method: Adopting a first-person deep systematic phenomenological approach, this study tracked the researcher's own 12-month self-healing cycle as the temporal framework, strictly following the logical loop of "case evidence → law extraction → model abstraction → tool implementation," synchronously completing theoretical construction and systematic self-healing. Results: Three core variables were identified from the case's natively generated experience: the Intrinsic Anchor Point (M), Action Direction (F), and Core Expectation (Y). The ontological M→F→Y steady-state closed loop and the operational Y→F→M optimal adjustment path were clarified. The MFY Three-Variable Steady-State Model and the M-F-Y-F-M Spiral Promotion Model were constructed. The First Priority of Anchor Point axiom and the "Expectation Redirection and Reconstruction" meta-intervention paradigm were proposed. Conclusion: This study provides a scarce, purified natural experimental evidence for the core axiom of humanistic psychology — that individuals inherently possess an endogenous tendency toward self-actualization. It transforms the abstract concept of self-actualization into a testable, operationalizable middle-range theoretical framework, opening new research directions for psychological steady-state maintenance and crisis intervention.
