Anon,
1. Look after yourself. Eat well ( try to eat some decent meals), sleep well ( make sure you're giving yourself enough hours to have the energy that you need for the next day) and try to do some weekly exercise, whether that's walking, going to the gym or joining a sports society.
2. Talk to different people. Sit next to different people in lectures and seminars. Make an effort to learn people's names. Attend some social activities. The more you get to know people, the easier it will be for you to adjust and to feel more at home at university.
3. Put in the hours for your studies. It's great to be independent and to be free to do what you want to do, but you are at uni for a reason.
You don't want to have regrets at the end of your year or your degree, so do give enough time to your studies, revise throughout the year and do visit the library.
All the best,
