One of my best friends copies me,always asks me to come over,and is insecure so she

[Connie]

insults me? Help? She's a really great friend any other time and when we first met, she was really cool! I just get so fed up that she's always asking me to come over and I always say no or make up an excuse cause I just hate seeing her face. She copies everything I "say". Even though that sounds stupid but I can't think of the right words to describe that. And she copies all the things I wear and always asks me to borrow stuff and I say no.(If I let her borrow my stuff people say they like it and she just says oh thanks like it's hers when i'm right there) It might seem like minuscule stuff but it gets on somebody's nerves when it happens a lot. Now I just can't be the same around her and it sucks! I never ever feel like hanging around her cause every time I do that hatred is like the only thing I think of when I think of her. To make things worse every time somebody compliments me around her she has to say something insulting to me like if somebody says you're pretty or I like your hair she says something like your head is huge or you look like a penguin right afterwards,I don't just take it whenever she says things like that,I stand up for myself but I can't seem to have enough will power to say the big picture thing!I can't even say what I like in a store in front of her or she'll run off and by it the next day and act like i've never seen it before. The worst thing is she copies my art right after I do it and always tries to "top" me in art class. It's the WORST thing ever because it just makes me so angry when she copies all the things I create. When somebody compliments my art she ALWAYS has to say something bad about it even though she's the one copying it! I don't know what to say to her anymore and I just hate being around her and she's the kind of person where friends mean everything to her because she feeds off them.She's really the only person I hang out with around here though, I don't really talk to anybody else! I don't know how to even start this conversation with her,maybe when we get into a fight idk?God i'm in a pickle! What's weird is that it's exactly half and half with her, she's really nice and a great friend when we're alone and just hanging out or something,but when we're with people or something she always has to be the better one or something and she has to feel superior and I'm sick of it.
