Ask for help from your family if possible in letting you occasionally just isolate and immerse.
My family wouldn't understand that, so I play hookie.
Twice a year, I schedule a vacation day that I don't tell my family about. I act as if I'm going to work like normal, but I spend the day at the art museum or sitting in the park reading, or something else that doesn't involve anyone else.
And then some day someone will recognize you somewhere, tell your wife "hey, I saw reaperducer at the park today!", and then she will think you're cheating on her.
I mean, that sounds great, I can totally get behind this in a way.
My big thing is being able to protect my sense of autonomy, even when I'm responsible for things or obligated toward others. If I literally can't take a day away from my phone or without telling people where I am, I've found myself in a risky space emotionally. So I'll occasionally leave the phone at home, or go hiking from sun up to after nightfall alone with the phone off, only maybe telling someone (including my spouse). People need their own space.
In addition to my previous comment, burnout seems to happen when you're working a lot on something you don't really control the outcome or reward of, along with the presence of some force that gradually erodes your sense of autonomy. If you feel like someone else is the arbiter of not just most of your energy, but all of it, over a long enough period of time, you'll grow to resent yourself, those people, and the work.
