Talking about people in my family

I wanna cry

So at school I have a friend group you know. But the thing is sometimes I feel left out, like they all are friends and there in the same class, then theres me being in a different class. But you know some people in my class are friends with them to. I'm just to scared to tell my best friend, because those are all her friends, I dont want her to feel guilty for me. I'm also to scared to tell her because I dont want her being mad or I'm saying this because I want to be more popular, no not at all. Like I love her and it's okay for her to have other friends, but idk. They all seem so happy together and work well together. I also dont want to get into drama either because I'm scared that I'm gonna get in trouble by the teachers and let me tell you something the teachers at my school DO NOT MESS AROUND ! She's literally the only person that talked to me after my friend group that she was in also, fell apart back in 4th grade. So Ang if you're reading this I hope you understand, if you dont that's okay :) You will still be my bestie <3
