Burnout, compassion fatigue, and substrate collapse

Burnout and compassion fatigue are often framed as moral exhaustion or “caring too much.” In FPE terms they are usually \(\Phi\) failure plus denominator overload — sometimes misread as numerator problems (“try harder”).

Three-layer model

Layer	Symptom	FPE
Cellular \(\Phi\)	Sleep debt, illness, HPA dysregulation	Bottom-up coupling fails
Cognitive \(\Phi\)	Rumination, poor WM, no recovery	Self-\(\mathcal{D}_{KL}\) high; \(\eta\) collapses
Relational \(\Phi\)	No secure co-regulation	Every social task costs full \(P_{in}\)

Burnout is when all three trend down while demands on numerator stay flat or rise.

Compassion fatigue = empathy without boundaries

From Part IV-B:

Empathy is the operation by which one agent reduces \(\mathcal{D}_{KL}\) with respect to another’s state before costly downstream evidence.

Compassion fatigue is when that operation crosses the Markov blanket:

Agent absorbs others’ prediction errors as own
Pays \(\mathcal{D}_{KL}\) on ISM continuously
\(\Phi\) erodes (Figley; “misdirected immune response”)

This is not “too much empathy” but empathy without Chapter 31.1 boundaries — Rescuer geometry at scale (nursing, activism, parenting).

Misdiagnosis: “raise \(P_{in}\)” (grind harder)

Organisations often respond to burnout with:

resilience training
productivity hacks
“self-care” as another task

If \(\Phi\) is down, pushing \(P_{in}\eta\) is internally contradictory — the agent lowers substrate to fund behaviour. Timeline: days to weeks to collapse.

Cheaper interventions (usually):

sleep, food, medical care
reduce \(C\) (unresolved conflicts)
lower \(\omega\) exposure (scope, hours)
restore \(\Psi\) (toxic manager, unsafe ward)

\(\mathcal{R}\) in helping professions

Factor	Burnout risk
High other-\(\mathcal{D}_{KL}\) load	Trauma exposure, ambiguous outcomes
High \(\Gamma\)	Bureaucracy, moral injury, unresolved caseload
Low \(\Psi\)	Under-resourced systems
Suppressed assertion	Cannot say no to caseload → people-pleasing

Moral injury is high \(\mathcal{D}_{KL}\) between institutional \(Q\) and witnessed \(P\) — the organisation’s model and reality diverge; the worker pays correction cost.

Depression overlap

When \(P_{in}\eta < \omega \mathcal{E}_\Sigma\) persistently, the node consumes internal information (Lemma 1). Clinically this overlaps depression:

not “laziness” but thermodynamic insolvency
aggression turned inward = attacking own \(\Phi\)

Treatment must address both substrate and coupling, not only cognitions.

Recovery sequence (FPE-practical)

\(\Phi\) first — sleep, safety, somatic care; reduce stimulant masking.
Lower \(\Gamma\) — finish or exit unresolved obligations; shrink \(C\).
Lower \(\mathcal{D}_{KL}\) — honest limits with team/family; stop performative OK-ness.
Reintroduce \(P_{in}\eta\) — small assertive wins after tonic budget returns.
\(\Psi\) politics — if environment cannot change, exit may be the only \(\mathcal{R}\)-rational move.
