Hi I need help (crying)?

Hi my name is Julia Brooke Brooke for short anyway I used 2 have a very close best friend I don't know why were not friends anymore anyways here's the story, me and Sam (best friend) are in show choir and we were picked to do a qurtet with Mickey ( other best friend) and Amanda ( another of my best friend were closer than me and Mickey) so anyway me and Amanda are studying the music well Sam and Mick are playing on the comp and talking!!! So Sam says how about u include me and Mick! But me Amanda were trying too and giving them ideas but they weren't listenin !!! I said that very nicely then she ran away crying! And the show choir teach asked for us 2 show her how far we got but Sam said no we can't perform ok so we fight alll night ( not really she just kept insulting me) so anyways she says sorry wil u be my sista I say no so at school I was buying a dozen of Chocoalate peace sign lollipopsand guess whos selling them 2day her mom!!! So her mom was like bribing me with compliments so I felt bad so I gave Sam one lala so everything was good we hung out that day then the next day Sam wouldn't talk 2 me I had no clue y! So Mickey mad a rumor saying I use her and I'm pretrnding 2 be her bff which of course I wasn't so I tell Mick to tell her it's a lie she does and me and Sam are still friends with Mick and so anyway she replaced me with this girl rose who she told me she always hated her! So ya
