The Differential Diagnosis — Naming What You're Actually Dealing With

Develop the meta-skill of naming what you're actually experiencing. Most engineers conflate depression / grief / burnout / anxiety / normal-life-difficulty into "I'm not feeling great." The cures differ; the misdiagnosis costs years. Build your baseline with validated instruments, your decision tree for professional help, and your crisis-resource card. Differential diagnosis is type-checking for emotional states. "Just take care of yourself" is non-actionable until you specify the type: CBT for depression, grief therapy for grief, structural change for burnout, EMDR for trauma — different handlers for different exception classes. The threshold is your circuit breaker, and the decision tree is the runbook written before the incident. When the metrics cross the line, the system pages the on-call (the clinician). Not paging the on-call when the threshold is crossed is the failure mode — for production systems and for your own mind alike.
