First day of 7th grade, any tips?

I have a cute outfit picked out : Aeropostale shirt and a pink undershirt with American Eagle skinny jeans and Yellow Box Flip Flops or my grey Converse shoes with the rinestones on them. I have a place in the hall to meet up with my friends. I don't have a locker so I need help with what to bring and must haves for a school purse. All I have in my purse is Tampons Lotion and money for the consession stand lol weird combination I know. And I am into acting and I go on quite a few auditions every week and I might have to miss school alot or get checked out and I don't know how to explain that or catch up with my work. If I tell my friends I go on TV auditions They'll never stop bugging me. When they saw me on an Aquafresh Toothpaste commercial they bugged me for months. It wasn't so bad last year because I didn't have an agent so I didn't get to go on many auditions. How do I deal with all this? And how do I get boys to like me? Thx!
