School is soon and im not excited

My school starts in a week.... I'm not ready for this : ( my sleep schedule is a mess, I don't remember anything I've learned from the past grade, and I just got back from vacation which means I don't have a lot of clean clothes and I'm still adapting to my own home. I'm going into a big school, and SOO many other kids from different schools are coming. 

Im not saying the kids are bad, but I don't know if I'll adapt to them quick enough. And did I mention band? If I'm gonna do that, art club and the smart kids club I'm already forced to be in... My schedule is gonna be a mess! About band, I'm playing clarinet! Apparently clarinet runs in the family, because it's what my grandma and mother played. But I have a big problem: my best friend is gonna be in band! (He's a boy and I used to like him a lot lol) I don't know if I still like this guy, I don't even know if were just good friends or if I really have a crush on him. This situation is complicated, my schedules a mess (im also probably gonna do that book club too), there's new people and I can't take the fact that its in a week... Idk what I'm talking about, and if ur still reading then I probs wasted ur time. But if ur still here, gimme tips bc I'm stressed! Xp
