Hi there!
I'm so sorry you're feeling this way.
You are not the only one feeling this way.
Firstly, I'd recommend to join clubs or societies. Universities offer many of these in order to build communities between students. Maybe there's a club that might interest you?
Secondly, have you tried starting conversations with anyone from your course? Perhaps they know groups of people to whom they can introduce you thus expanding your circle.
Thirdly, there is no shame in seeing a counsellor. It is great to speak to someone external who is trained to offer tips and guidence to individuals in a similar situation as yourself.
Lastly, it might sound hard but also obvious but please don't give up and don't forget to put yourself out there. Try being as social as possible and join various events.
I hope I managed to help!
Let me know if there's anything I can do (I used to be a student myself so I was in a similar situation as you).
Best of luck,
Melanie
