Friend troubles (Big Points) Please help! Answer ASAP.?

I'm scared that I won't have anyone to hang out with at recess because I got in a fight with my best friend who I follow around and shes very popular, im not really popular. She tends to hold grudges a long time, and people have there own little groups. I'm shy when it comes to socializing. My schools very small about 120 kids P-8. I'm in grade 6 & i'm 12 years old. Please suggest what I should do, because I can't even sleep without thinking about tomorrow, and I start to cry at the fact I might have to stand along like a loser. It's already 11:08 so please hurry
