Hello,
I am sorry you feel this way, as an international student I also struggled to make friends in my first year.
Other than societies and sport, you can try to make friends through the library (as often there are social spaces where you can just chat and meet people). As a medical student, I made a lot of my friends procrastinating in the library and eventually I joined study groups.
Another unconventional way to make friends is through apps like Yubo or Peanut, and meet people near you with common interest.
In addition, try to see if your universities offer any group activities, or maybe even pop a text on the group chat and see if anyone would be happy to do any activity.
If you ever feel like you want to speak to someone, make sure you reach out to your university's support services. They are always helpful.
I really hope it works out! It gets better with time❤️
Haya
