Just Vent | Just Venting

Annoying girl keeps sitting next to me in class and trying to talk to me! I dislike her attitude because she tries way too hard to be "cool" to the point of lying about every aspect of her life and she constantly contradicts herself! My friends don't help either because they notice her affection for me and they say things like "your girlfriends here" which I think she misinterprets the sarcasm. I don't want to be mean because she must be stuggling with some major identity issues to chronically lie just to impress others and I don't want to make her spiral even more downhill, but its getting soo much worse cuz i'm being stalked to the point where I'll notice her following me to classes and she talks to the teacher and forces her way into my group projects! She even changed home rooms and is now in mine!
