Slight side track, but on the diabetes thing...
Some well managed diabetics will need no further support at all. Others will be unstable, and however hard they try to manage their condition they can't keep their levels right all the time.
As a student living away from home in shared accomodation there are things that can make a massive difference, like a fridge in own room, partly for keeping food supplies in and safe from others 'borrowing' and for any medication that may need refrigerating (I know most insulins now don't, but some do), or even something like a contact with someone every morning to make sure they woke up from the night before.
If you hypo'd in your sleep at home, someone you live with would notice you not waking up in the morning, if it happens as a student, chances are no one will.
It's a good example of how the same condition can effect people very differently.
