Worried about going back to school tomorrow

Worried about going back to school tomorrow Tomorrow is my first day of tenth grade. I have all new teachers and an all new class. I also am in a pre IB program which is harder work at a faster pace. This includes a French drama class 😐. I am worried I will have to introduce myself in front of everybody. I can say my full name just fine, just not my last name on its own. If they ask to say an interesting fact I would have to say I play basketball cause that’s the main thing I do but one of the letters I struggle with the most is b. I am scared I will stutter in front of everybody and make a fill of myself on the first day.
