Long-term harm caused by sustained educational stress or exclusion. Debility operates through accumulated exposure to hostile environments, chronic accommodation denial, repeated exclusion, and ongoing invalidation of distress. Students experience deteriorating mental health, school refusal, trauma responses, and diminished capacity. Families experience burnout, financial strain, relationship breakdown, and occupational disruption. Debility represents the embodied cost of educational violence, often dismissed as pre-existing fragility rather than iatrogenic harm.
