8th grade! help! please!(ill give everyone thumbs up!)?

ok so im started 8th grade in 2 days. (its still in middle school at my school) and 1st of all i have ZERO friends on my team. Also i have no idea where my homeroom is because i have a latin teacher and she didnt have her own clroom last year so ill look so stupid looking for it! and we have a new princeapal and he took the school map of the internet so i cant find the clroom. Also i have a team called the "split team" meaning they have both 7th and 8th grade students so its realy small and we dont like have diff kids in each cl. We stay with the same kids in our period 1 cl for every single cl. So im so nervous! I know it will be alright but what if its not. I mean wat if i get a cl where im not friends with anyone and nobody wants to talk to me! ughh. So please wat should i do!? and how did u like 8th grade? thanks so much!!
