This girl in my cl?

Okay,I am a 14 year old girl(i'm using my friends account.),and there is this girl in my cl room,I am in the 9th grade.Her name is Candice,and she is annoying...I hate to say that,but she is,and she wears braces and when she talks,its so annoying sounding..like spit flying out,and it sounds like she is illterate..and mute(she barely can pronounce words right with them.)and she snitches on people alot,and she thinks everyone ''hates'' on her when really..no one hates on her,they just hate her.no one in our cl likes her,and i feel so bad for feeling this way towards her,shes annoying ,but we dont know why..is this even possible..?i feel bad for aving such feelings towards her,when she has no friends already..?help
