Post-traumatic embitterment disorder (PTED), introduced by Michael Linden, is triggered by a single life event experienced as unjust, humiliating, and violating basic beliefs—typically job loss, divorce, institutional betrayal, or legal defeat. Unlike PTSD (fear-based), PTED is bitterness-based: accepting the situation would mean accepting the injustice, making resolution structurally impossible from within the attractor.
The healthy ground state S^0 is defined as equanimous agency: acknowledging genuine injustice, grieving the loss, and continuing to function without the injustice as the defining event of existence. W_PTED arises when the injustice-narrative becomes the central organizing principle: each memory review simultaneously re-traumatizes and gathers evidence for a fundamentally unjust world.
Nine formal propositions characterize the basic belief violation mechanism, the humiliation loop as dual-function architecture, vindication-seeking as basin-maintenance paradox, social defeat amplification, and return paths through wisdom-based cognitive therapy, meaning reconstruction, and acceptance.
