performing?

I finally got my computer back. This morning my mom had to do stuff on my computer for my lil sis's bookmark competition thingy. So basically i had to change my password (cuz i like my password now and wanna keep it) and give her my computer which she has full access to, my history not deleted (which iz bad...but she used mozilla instead of internet explorer, my heart almost stopped in relief...u dont wanna kno my history...) and i had to leave for school so she cud've done ANYTHING she cud've changed the password so i cudn't use my own computer anymore. But she didnt cuz i guess she still trusts me which i feel a little guilty about cuz im on here rite now wen i shud b doin homework when shes @ my sis's piano lessons.
ANYWAY, i shudn't trust my mom with skool. She said im failing and i cudn't believe it. But she took my comp anyway, even though i had all a's and one tiny little b. she wuz counting the assignments. I wuz like wtf, all a's and 1 b is rlly good i think, and she wants more (damn parents that care about me...:'(...) so besides that wats only rlly been happening with me iz that i mite perform in the talent show. I rllllyyy wanna do famous last words, i have the whole thing worked out in my mind but the guiatar is too hard and i cant find anyone to do it with cuz there already doin sumthin els. So me and my frend are goin to ATTEMPT to play are we the waiting and shes a rebel by green day. He is obsessed with green day, mainly the american idiot album. I'm afraid if i get to picky, he mite realize how sik ubssesed i am about music and stuff. So probly in about 5 months we mite perform 2 songs. We kno nuthin bout guitar even though i have an electric guitar, dont have a definite drummer anddddd......he cant fucking sing for his life... even though im singing one song, hes singing the other...so i dont kno how its gunna turn out cuz my hope r up (again) that i mite b able to finally perform live. Soo basically does any one have any tips for a good performance (besides goin crazy, cuz i will go crazy if we ever get there, no matter if the principal iz there or not, no matter how many parents we are willing to do ANYTHING 4 a good show)
Ok another thing iz that there is a little christmas dance thingy. I went last year but it wuz miserable cuz i watched da guy i liked for da whole year dance and make out with sum other chick. But this year i have a boy frend and stuff so i HOPE its different...
ok that wuz kind long-ish....but i im gunna go actually get sum work done:P
