How much do you have left on your plate before the end?

How much of that *must* happen, and how much of that would not be missed if it didn’t? Cut those things.

If you’ve got administrative things to do, make a list, set a timer each day, and do as much as you can in that time period as you can, and when you leave, don’t take it home.

Spend some time doing something you enjoy with your communications device turned off. I also recommend finding some outside time. I’m not an exerciser, but even I drag my large rear end outside to get some sun and fresh(ish) air for my mental health.
