Hi! I'm sorry to hear you're having a hard time with university, it can be really difficult to adjust to such a new way of living. My advice would be to join some societies, or find something extracurricular that you are really passionate about, whether its volunteering, work experience, sports etc. It makes finding friends a lot easier as well as giving you a break from academics. I personally struggled a lot in my first semester but things gradually got better throughout the year, now I'm in second year and things are considerably better! Not everyone has the best time immediately, for some people it takes more time
Hang on in there, and good luck.
