hi im in 9th grade and i thought that i had everything until when my friend tallied me that everyone thinks that im a loser and my other friend heared some people say that im loser too and now my friend is trying to show of her self that she has friends more than me just because she heared some people say im a loser and then she backstab me and talk to populer kids and think that she's their friend but they are actaully my friends more than her and she thinks everyone loves her but i know what they say about her and how gets in everyones nerve (oh and by the way the other friend is my second cousin) how can that all happen in one day that u figure out that everyone thinks ur a loser and how can i give a message to my second cousin that im not the one who's a loser she is
