I’m in the middle of it right now. It sucks, but the best thing to do is hunt down the Disability office as soon as you get acceptance and put in your paperwork for accommodations. If you get a say, ask for flatmates that will work with your sensory needs, i.e ask for people who want quiet if you are sensitive to noise. If your uni allows it I would learn to cook if you haven’t already a few simple meals that are sensory friendly for the days the dining hall isn’t serving something you can eat. And don’t feel pressured to disclose or not disclose to anyone who you aren’t legally required to to access accommodations.
