This is just a suggestion, but I would get your own room!!! When I went to college from 1990-1994 I had my own room in the dorms and then my own room in my sorority house. Do not fool around with dealing with your roomates schedule. You need your sleep, privacy, do not want to catch a cold, etc. Having my own room was a major plus, I liked it and so did my boyfriend at the time, my bad! But, seriously, you do not want to have to catch any colds and deal with being sick, you have to do your therapies and do them the correct and thorough way; so I would not even try to deal with a roomate. What if the roomate is up all hours, your dorm is grand central station etc.
Use the disability services to your advantage so you can be healthy and enjoy college life. I even went as far as getting a handicapp sticker to park my car. The parking lots for students were so far away from the campus that is literally defeated the purpose of drving instead of walking in bad weather. So, I did get a temp handicapp sticker and was able to park in the lots right smack on campus within a few steps to my classes. It was a great help to me and even my friends enjoyed the perk!
Good luck and have fun!!!!!!!!! But your health is #1 and you will not be able to enjoy let alone get thru school if your sick, worried about treatments and doing them half asssed cause your afraid someone might come barging into your dorm and you for sure do not want to be around a sick roomate!
Use your best judgement, that was just my experience and suggestions!
