Hi there!
I'm sorry you're feeling this way.
You're not the only one feeling lonely or anxious throughout your first weeks of university. Remeber this is a big change for numerous studnts.
Have you tried joining any clubs or societies at your university? There should be a few that might interest you.
Additionally, classes just started so there is time for you to get to know your fellow coursemates. Have you tried starting a coversation with someone? Perhaps they have friend groups to which they can introduce you.
Also, unfortunately, many of these "friend group" won't last until the end of the year, as so many people change throughout university, it's inevitable.
Lastly, don't be scared to get out of your comfort zone and try new things. Maybe befriending someone with a different taste in music, fashion or aesthetic could be a great opportunity and the start of an amazing friendship!
I hope I managed to help!
Let me know if there's anything else I can do (I just finished my 3rd year so I was in a very similar situation as you).
Best of luck,
Melanie
