Quick answer
Burnout is exhaustion and depletion from chronic overload — you feel drained, cynical, and empty, often improving when the pressure genuinely lifts. Anxiety is apprehension and worry that persists even at rest and often without a clear cause. They overlap and can coexist, but their core feelings differ: empty versus on-edge.
The signature of burnout
Burnout is a state of depletion from prolonged, unrelenting demands — classically overwork, but also caregiving or chronic stress. Its hallmarks are exhaustion (physical and emotional, not fixed by a night's sleep), cynicism or detachment (feeling distant, jaded, or numb toward work or people), and reduced sense of accomplishment (feeling ineffective, that nothing you do matters). The dominant feeling is empty, drained, and running on fumes — you've given more than you can recover from, and the tank is dry. Burnout is fundamentally about depletion.
The signature of anxiety
Anxiety, by contrast, is fundamentally about apprehension and threat. Its hallmarks are excessive worry, a keyed-up, on-edge feeling, restlessness, racing thoughts about what might go wrong, and physical arousal (racing heart, tension) — often present even when you're supposedly resting, and sometimes without any identifiable cause. Where burnout drains you flat, anxiety winds you up. Where burnout often improves markedly when the external load genuinely lifts (a real holiday, a job change), anxiety frequently persists regardless, because it isn't only about external demand.
Overlap, coexistence, and what to do
In practice they overlap and often coexist — chronic stress can produce both, burnout can include anxiety, and exhaustion and worry feed each other. Two rough tests help: does it lift when the pressure truly lifts (more burnout) or persist regardless (more anxiety)? And is the dominant feeling depleted-and-empty (burnout) or apprehensive-and-on-edge (anxiety)? The distinction guides the response — burnout needs recovery, rest, and reducing the load; anxiety needs the worry patterns addressed directly. But both, if persistent, warrant taking seriously and often professional support, and the two together are common. If you're struggling to tell or to cope, that itself is a good reason to talk to someone.
When stress needs more than self-care
If stress has become constant, if your sleep, mood, or health are suffering, or if you can't switch off even when the pressure stops, it's worth talking to a professional. Chronic stress responds well to structured help, and getting support early prevents it from hardening into anxiety or burnout.
