I don't know your full situation, but as someone who has gone through full-blown real burnout: it's not worth it. In this economic situation, we do need to grind to keep our jobs but if you're getting close to burn-out I would *strongly* advise prioritizing avoiding burnout.

I went from being a passionate programmer spending all my free time working on code, to be unable to write a single line for even my most loved personal projects for 6 months. Fully awake, in the middle of the day, I would boot up my computer and within 10 minutes my body would put itself to sleep. I'd wake up hours later with my laptop barely past the login screen. It took me 6 months before I could do personal projects again. 1 year before I could do professional work again. 2 years before I could juggle both. I've fully recovered (or at least I did right before LLMs hit the scene), but it takes a lot of time and I lost a lot of money not working for that year. If I could go back in time, I would have quit that job earlier because it is far easier finding jobs as a passionate developer rather than a recovering burnout.
