Burnout isn't a productivity problem. It's a nervous system problem. You've been giving from an empty cup for so long that your body has started shutting systems down to protect itself.
The standard advice — take a holiday, set better limits, do more self-care — often fails because it doesn't address the underlying patterns. Therapy for burnout goes deeper: regulating a nervous system that's been running on fumes, and examining the identity wiring that made relentless output feel like the only option.
Often those patterns involve self-worth tied to output, relational dynamics (you're the one who holds things together), or unprocessed chronic stress that never had a chance to discharge from your body. Somatic therapy is particularly effective here — because burnout lives in the body as much as the mind.
