One thing I have been looking at is what I do on my days off. Am I making the best use of those days for both achieving tasks and resting?

Not really.

Something I got from Hannah Marcotti a few years ago, is where you do self-care for yourself in the future.

It's things that will make your time more effective in the future as well as your days hopefully running a bit smoother and therefore with a heck of a lot less stress.

Essentially, what can you do this morning to make our day better later and what can you do today to make your day better tomorrow?
