How it can feel
- Bone-deep tiredness that sleep does not fully fix.
- Paying for a short outing with a day in bed.
- Cognitive fog rising as energy falls.
- Looking “okay” while running on empty.
Day to day
- Work, parenting and social life shrink to fit the battery.
- Boom-and-bust cycles: push on a good morning, crash by evening.
- Guilt about rest — especially when symptoms are invisible.
Why this can be FND (simply)
Fatigue is not laziness. Nervous-system load, disrupted sleep, pain, deconditioning and the cost of symptoms all drain capacity. Chronic fatigue patterns can co-exist with FND.
What can help
- Pacing and planned recovery, not heroic overdoing.
- Sleep support and treating night-time symptoms.
- Breaking tasks into smaller chunks with rests.
- Communicating energy limits to work and family.

FAQs
Why am I more tired the day after activity?
Delayed crashes are common. That lag is why pacing looks at the whole 48 hours, not only how you feel mid-task.
