I'm experiencing it bad right now. Some of the stuff causing me to feel stressed will pass with time but I'm feeling awful now :/
I can't take more than a day off from work, which might be pushing it anyway, and I have so much work to do in the next week (possibly weeks? Idk yet)
Even weird advice would be appreciated 
I got this awesome little compact floor treadmill in my living space now and it makes it so much easier to just jog whenever
Smoke lots of weed and go goblin mode regularly, ideally before burnout begins. Prevention is the best medicine.
Being aware that you're about to burnout before you do allows you to prepare and minimize the damage. Figure out some warning signs that happen before you burnout: e.g. you start feeling less inclined to do things you enjoy, you start sleeping more hours, etc. If you're gonna burnout, start taking on less tasks and start setting smaller goals and expectations of yourself.
This is assuming that you can actually lessen your workload somehow. Idk how to stop burnout if you have no choice but to be worked to death.
Also regular exercise helps build your capacity for work in the long term, and becomes something you can reduce/drop when times get tough.
Edit: also cutting out alchohol helps me. the smoking weed recommendation might not necessarily be a good one. weed helps me get thru the burnout but makes my depression worse
i think the only non goblin mode part of this is the self care stuff, people usually let that slip but i think its the only thing worth prioritising when burnt. tho when googling goblin mode it seems to fit with some definitions.
Get off the Internet and read a book. This is a more extreme measure, but microdosing mushrooms really helps me.
Pick something small and close to you and clean it. Like your desk/office. Even digital (clean up a photo album, desktop etc).
For real, though. I've been putting off a break for so long because I got a lot on my plate and I always gotta be the responsible one. Well, now I'm eating garbage tacos and drinking whisky because I held it off toooo long.
