I wish you the best, it’s okay to be hesitant or nervous and everyone will be, just focus on not getting lost and know that most people are kind and willing to help you if you need it.
If you don’t want friends or don’t want them now, the first day is not the only time to make them and you can have them through clubs, activities, work etc. it’s not the end of the world.
My best advice is to approach things with a light heart, drink responsibly (if you are drinking), respect your boundaries (don’t let people cross them) and def dont take any early classes.

I gonna go to the university tomorrow (( am so scared I dont wanna make new friends
