Get a mobility aid if you don’t already!! They’ve helped so much with the fatigue especially, I have a cane and a pair of forearm crutches but my go to has really been just the single crutch, it’s got more stability than a cane alone. Life changing. Also lots of naps, accommodations if you can get them, and not trying to force yourself to do stairs and things to save time or “act normal.” Scheduling time for meals at the dining hall after class/other scheduled things helps a lot as well
Since I can never convince my body it’s worth the energy to leave my building just for food. Also keeping nutritious food on hand in your space and with you in general is good, as well as water. I’ve also had luck with KT tape and compression gloves for hand/wrist pain that I get from writing and typing for a long time.
