Welcome to Uni!
It's not like school, and you probably are further away (having gone to high school in the middle of the city for six years, it didn't bother me much last year, but obviously not everyone is so lucky).
Everyone takes a few weeks to adjust. You simply aren't in the same environment that you've been in for the past six years. If you can adapt, then you're good. What I'd recommend is this:
*Hang in there. Eventually you get used to it.
*Make use of any time off during the day. If you have a 2 hour gap in the middle of the day, perhaps you could use it to study. If you've already got 2 hours out of the way, you won't have as much to do when you get home.
*Try and get a bit of rest during the trip.
*(My general advice for everyone): Start studying from day 1. Far too many people will do nothing until stuvac, only to realise they now have 1 week to learn a 13 week course. Not a good feeling.
The rule of thumb in second semester is this: If you haven't started studying when the Jacarandas bloom on Physics Road, you're stuffed.
