I hate today!!!!!

this day started out so good. i woke up when my alarm went off, i got my cousin up and ready for school and she didn't miss the bus, 1st and 3rd period were a lot of fun and lunch really couldn't have been funnier. Swing choir was the same amazing class it always is and then in 5th period we started a movie i have just been so excited about. Then my day turned to crap! Aunt flow decides she is going to visit and of course i don't have anything. My math teacher wont sign a paper letting me go on a swing choir trip and although i understand that she is mad about my grade i don't get why she doesn't try to help me... i'm not the type of person who goes and ask for help. i'm scared that everyone will think i'm stupid or something like that. She doesn't help me when she can clearly see that i don't understand. like i see that she could think that i was just lazy when i don't turn in my homework, but if i'm failing every test shouldn't that be a good hint that i just don't get how to do it? I'm scared that if she wont sign it then i can't go...I have to go on this trip. Soon i won't be at this school and swing choir is the only thing i like here, i have to make the most of the things i get to do with it...
