every first day of school is like that. everybody is nervous. listen, i didn't like middle school much at all. it was because i was in a shell for a long time before that, extremely shy, so middle school got me out of that, but it was hard for me.
i wasn't bullied or anything. in fact, quite the opposite. it seems i attract people, i guess this is just what kids like to do when they see somebody different from them (i'm tall, so usually that's the first thing people tell me lol)
i'm in high school now, i am very sociable. unless you're an idiot who bothers everybody, (not like asking questions for help, just really an idiot) nobody should judge you/nothing should happen to you.
