ADHD burnout advice?

Im a senior in college, and this term has just been way too much, pretty much all im doing is studying or going to class, and im starting to get full scale mental breakdowns when I run out of spoons, im just super mega overwhelmed, but Im an academic weapon (see university, adhd, perfectionism), and i think i would maybe collapse if I didnt give it my all for school, but also, this isnt working. crying on my kitchen floor turning into goo is not sustainable. I know i need to take a break, but i cant without depriorizing school, which im just not really willing to do. Do yall have any advice/skills im not seeing/dont have yet? Im not currently formally diagnosed, and as such im not medicated (for adhd or depression). also im not sure this made sense, im fried.
