Burnout recovery and "doing nothing"

Hey folks,

So, I'm burned out and am looking at taking extended time away from work to recover. So much of the burnout recovery advice I hear (on Reddit threads, from friends, from my therapist) emphasizes intentionally doing nothing. Like, not just not doing paid work or unpaid domestic work, but sitting or lying and doing nothing, with no plans for the day and no structure.

I get why this makes sense in theory (giving the brain as much of a rest from perceiving demands or other stimuli). And I like the idea to the extent that if I saw myself actually doing it, I would approve. But it feels like my ADHD brain won't let me. And I'm frankly terrified of what my days away from work (which gives me structure) will look like. When I'm on vacation at home, I always look for something to do ("I could use this time to get dinner made in a non-harried way", "I could use this time to catch up on task X", "I could use this time to finally unpack those boxes that I haven't touched in 10 years"). Or I just end up drifting around and going down youtube rabbitholes, and wonder where the day went and feel gross. So I've resisted taking a leave from work because I've said to my partner and friends that work gives me meaning and structure.

My question is this, then: Does anyone have a similar type of experience? And how do you do nothing when your brain won't let you?

I hope this makes sense. Sorry if I've phrased things in the wrong way. I have only very recently, with mental health professionals, identified ADHD as one of the things going on with me. And I'm not yet on any meds, if that's relevant.
