Whether you commute to school or live there, one priority to add to your checklist is communicating with your professors about your diabetes. It's something each professor should know about, just in case you have to eat in class or test your blood sugar. Also, it's good for them to know that your pump isn't a new high tech cell phone or that your syringes aren't for illicit drugs. It's your own personal choice whether you want to get in touch with the disability department or not, but it is an option. They will help provide you with extra time during exams, and give you letters to give to your professors in most cases.
If you live at school and are getting ready to move into your dorm, there are certain things that you should pack extra of, and it's not just underwear and socks. Like I said in my first blog about traveling, always pack extra medical supplies. Count out a rough estimate of how many of each thing you'll need. Then round up. Double it. Pack a secret stash in one of your backpacks. It's always good to be prepared in case you can't get home, your mail gets lost, or you use up more supplies than you had planned. This is especially important when it comes to low supplies. There's no worse feeling than being low at 3am and not having juice at hand. And your roommate who has to run and get you gummy bears won't be so happy either.
Speaking of roommates, probably the most important person that should know about your diabetes is her/him. Your RA is a good person to be in the know as well. Now don't panic and make this into a bigger deal than it has to be. You don't have to approach your roommate on the first day, glucagon in hand, and tell them they must stab you with it if you ever pass out or seize in their presence. It can be brought up in casual, introductory conversation. And chances are once they hear about what diabetes is (if they don't know already) they will take it calmly and collectedly.
All of this may seem like a lot. But like any other big part of life, it is just something that you have to put a little extra effort and time into. After you get into a daily routine at school, diabetes management will fall into stride with everything else. Then you can focus on what's really important--that GPA.
