Unless you want to keep living that way I would highly recommend to do hard disconnects from time to time. From my experience there will be a short disruption but then other people will step up and overall things will keep working nicely. You may also get seriously sick one day and then things will get forced too.

I have had a lot of times when I thought I was indispensable but things were just fine without me. This can be liberating because you can now focus on other things and don’t get stuck with the same stuff.
