Yeah - that’s what I mean by it being a self reinforcing cycle. I have no kids which helps hugely, but I have a checklist of things to do that I made during a period when I was feeling good and had good habits. I don’t think it matters what that list is, but I’ve found that doing those things on that list has 0 impact on my mood that day but “would you rather be tired and not exercised than tired and exercised” is a good motivator for me.

Some element of it is not taking advantage of your body when you are restored - if you empty the tank every time you’re feeling good you’re always going to yo-yo a bit.
