i'm an experienced disabled person (EDS, CFS, POTS, chronic pain). here are some of the things that help me get by as a college student (note: i use a wheelchair and a cane most days. i also am fortunate enough to have decent medical care, meds, and my aforementioned mobility aids)
shower chair. i can't stand for long enough to shower, and especially not if it's a hot shower. i got a cheap one off of amazon that has three legs and a plastic seat. that plastic seat makes it super easy to keep clean. i know there's a weird sort of embarrassment about sitting in the shower, but PLEASE, it is so much better than sitting on the floor in the shower or falling. in my dorms, there are two (2) showers with fold-down seats. i put a small towel down on the seat so i'm not bare-ass on this dorm bathroom surface, then i wash it down after.
normal wheelchair gloves are fingerless, which suck for winter. BUT, winter cycling gloves have the same cushioning on the palms and grip material and fingers. they're not super warm, but throw on a pair of thin gloves underneath (or, if you're like me, propelling keeps your hands super hot anyways).
an ice pack on the back of your neck can help with migraines and dizziness. i keep a small one in my freezer at all times. i tuck it into a hairband so it can be hands-free.
PLEASE adjust your cane/crutch/crutches to the right height. it helps so much with shoulder/elbow pain and balance. if it doesn't feel right, it probably isn't. the handle of my cane hits around the height of my wrist if my arm is just hanging down.
if you have hyper mobility, try high-rise shoes. i wear only high-rise converse and doc martens, which i can lace tightly around my ankles to keep them from rolling or sliding out of place.
(MENTIONS FOOD AND CALORIES) keep an easy, high-in-calorie food around. for me, eating on high pain days is essentially impossible. so, i need something that i can get myself to eat (like ice cream or canned soup or chips) that won't take any effort. ice cream is a great one for me, since it's sweet and cold and dense. even if it's not healthy, nothing is more unhealthy than not eating.
please, please, please find a community of disabled people. most of my close friends are able-bodied and, as much as i love them, they just can't understand it like other disabled people do. i found two great communities on my college campus, but i've also heard that support groups are a great way to meet people within the community
if you have any other tips, reblog with them. i remember the beginning days of my illness and how daunting all of this was. this is how we support our community.
