Burnout is not a mood. It's not a motivation problem. It's not a character flaw. It's not "you need to slow down."
Burnout is a physiological injury to your nervous system — the same way a torn ACL is a physiological injury to your knee.
For ten, fifteen, twenty years, your body has been running a stress response designed for short bursts — the kind your great-grandmother used for three minutes while a bear walked past her cabin. You've been running it for three decades.
Your body kept the receipts. Every single one.
A nervous system stuck in that state cannot be talked out of it. It doesn't respond to affirmations. It doesn't care about your gratitude journal. You can't mindset your way out of a stress response any more than you can mindset your way out of a broken ankle.
You don't need more insight. You need a protocol for the body.
