Lately I’ve been trying to sort out why everything feels mentally exhausting, even things that used to be pretty manageable. Answering messages, making basic decisions, keeping track of plans, it all seems to take more effort than it should. I’m not necessarily doing more than usual, but my brain feels like it never fully switches off.
The confusing part is that I don’t always feel obviously upset. Sometimes I’m just foggy and worn down, then I get frustrated with myself for not being more productive. Rest helps a little, but not as much as I expect, so I’m wondering whether stress is building up in the background without me noticing.
Has anyone found a useful way to tell whether this kind of exhaustion is mostly anxiety, burnout, poor sleep, or something else?

James, the part about your brain never fully switching off sounds familiar. I’ve found that mental exhaustion can build even when I don’t feel actively anxious, especially when I’m constantly keeping track of small tasks and decisions.
One thing that helped was writing down my sleep, caffeine, stress level, and energy for a week instead of trying to diagnose it in the moment. Patterns were easier to spot that way. If the fogginess continues or starts affecting basic daily life, I’d mention it to a doctor too, since poor sleep and physical issues can feel a lot like burnout.

Tracking it for a week sounds more useful than trying to explain every bad day while it’s happening. I tend to assume the fog means I’m stressed, but sometimes it’s just several nights of mediocre sleep plus too much caffeine.
I like that you mentioned small decisions too. I’ve noticed I feel drained after constantly switching between messages, errands, and unfinished tasks, even when none of them is especially difficult. Did your notes show a clear pattern, or was it more helpful just to see everything written down?
The frustration over not being productive can add a whole second layer of exhaustion. I’ve had days where the actual tasks weren’t that hard, but deciding what to do first and remembering all the little things left me completely drained.
I’ve found it useful to notice what happens when I remove some decisions for a few days. Same breakfast, fewer messages, one written list, and no trying to catch up at night. If that helps, it points toward mental overload more than just needing extra sleep. I’d still get the fogginess checked if it keeps going, since sleep problems and physical issues can look very similar.
