yes, it was such a relief! I remember my first day on a new school but I ended up meeting my best friend :).
But my first day this year was really okay, I was so nervous but I had a few classes, the teachers were actually really funny and I met some new people I hadn't met yet. I'm sure you can do it!
I always tell myself on a first day or if I go somewhere with brand new people ''Socialize as much as you can, act like you've known them forever and if you don't like them, then go away and meet someone new." If you try to socialize nice people will come around, even if you don't expect it :)
