If you feel uncomfortable, you need to talk to someone. There are few friends in the university, so you can get to know them through the gathering of fellow villagers. It is understandable that a person is homesick in a foreign country. If you are alone in the hotel, you might as well go out for a walk during the holiday.

I am a senior this year, and I am applying to study abroad. I've thought about this situation. Besides communicating with others and getting rid of loneliness, I think it is more important to learn to be independent and enjoy loneliness in a foreign land. Since you are a freshman, you should learn to take care of yourself independently and plan for your future. Family is very important, but one day you must leave home and live independently. Take the present situation as a test and try to integrate into the circle here.

Good wishes!
