starting high school😲😬😨

I have gone to about 6 different schools in my life (military family) and I'm going to highschool next year. my first day is on September 4th, I'm really scared even though I shouldn't be. I don't know why. Also all my friends are meeting guys and having boyfriends but I haven't even come close to getting one. I know it's not cause of my looks or body. According to me I'm not too bad, bit should I be having crushes on guys and stuff? I haven't had a crush since I was 7 years old.
