Hey
I'm 20 and in my third year of uni, 2 hours away from home! I was in halls on my first year, in a room on my own that was locked overnight! Nighttime hypo's have been a huge anxiety for me, I've had diabetes for 9 years now and thankfully I've only had one severe hypo (unfortunately overnight).
As long as you're checking your blood before you sleep, and it is running steady in the hours running up to bed time, that's the best thing to do
also, setting an alarm for 3am tests is a good idea, then you're not going the whole night not knowing how your blood sugar is.
Also, depending on how long you have been diagnosed for, you'll learn how good you are at waking up from hypo's in your sleep- the slight low, even in the 4's and I'm awake.
You just have to tell everyone as soon as possible that you have diabetes type 1. People are more understanding than you think and then you have people that know around you and can look out for you
you won't be 'weird' by any means- and if people are judgemental they aren't worth it, you have to put yourself first
Also if you're going to clubs and drinking at uni (especially during freshers week) just be careful with alcohol as it tends to make your blood sugar drop hours later.
Going to uni is an amazing experience, especially with diabetes, it matures you so much and makes you so much more independent and able to cope on your own. I know just how scary it is but you'll be fine I'm sure
