I can be really shy when meeting people so i'm scared i'll end up with no friends in my first year :/
Who on earth makes friends with people having known them for only a week?
Just be polite, give a big grin and initiate conversation even if it's only a "Hi!" Everyone else is in the same boat
The best thing I did before starting uni was join the freshers group on facebook for my uni and find people on my course. Then we all had a big group chat going, found some friends in that group chat and my those people have been my main group of friends ever since. I'm not sure how easily I would've made friends had I not chatted to them the entire summer before considering I don't live at uni, so it really helped me out. I made loads of other friends on other courses that way too. Then that gets the ball rolling because you can introduce them to other people you meet and they can introduce you to other people they meet etc.
As the cliche might go: a lot of people feel the same. Before you say hello to new people it can be very difficult but once you actually do it, you'll wonder what you were worrying about in the first place.
I'm planning on arriving as early as possible tbh.
A little, but hopping everyone else would be just as nervous. I always tend to be popular with people at the start before they get to know the boring, reserved and serious side of personality.
Don't worry it's really easy to make friends at uni as long as you are not antisocal
