I've started keeping a notebook where for every day I write down every 'task' I've done; anything that's a chore, that cost me spoons, or that could in some other way be considered 'productive'. The exact criteria don't matter for this purpose, if it mentally registers as a chore or task then that means that it would've functioned like one to my brain, so it qualifies.
And however weird it sounds, as expected, the lists end up being a lot bigger than I expected them to be.
I very much recommend doing this if you feel like you can't ever get anything done.
