It's super normal to feel a bit worried about starting uni and your first few weeks, as it can be a bit of a change from school!
During the first few days, you'll have a freshers week which is like a settling in week at uni. Freshers is a great time to meet the people on your course, your flatmates and have a look at some societies that you might want to join! Societies are a great way to make friends outside your course who share similar interests!
The first week can feel a little overwhelming at first since it can be quite a big adjustment but use it to find out what works for you! The first day / week you'll meet all the tutors on your course and get a taster of all your modules. This is also a good time to start figuring out how to best manage your time (this does take a lot of trial and error though!).
My best advice for building friendships would be to have a look at facebook groups for your course so you can start to chat to the people who you'll be with for the next few years (this is how I met some of my best friends now!). This also really helps to ease those first day nerves as you'll already know a few people!
I hope this helps!
