GAH IM MOVING TO A NEW SCHOOL AND IM SCARED?

So I'm going to 7th grade, I'm currently 13. It's a long story on how I'm in 6th grade and 13 years old, but anyways... I'm going to this school "Faye Ross Middle School". Currently at Cerritos Elementary. I know everybody is going to be new there, but everyone has been through everything together.... elementary at the most. I'm really scared. I'll probably only know 2 or 3 people there. It's really hard for me to make new friends. I'm really shy. It's not going to be the same for me, I'm going to miss all my old friends. We have all been through together. They're going to Carmenita Middle School. I'm just really scared. What if I don't fit in? What if I'll be that "outsider"? I don't know, it's just hard for me. Any advice? Thanks.
