Book With A Hispanic Emo Girl?

I remember reading a book with a new girl having trouble fitting in at school, but I just can't remember what it is, and it's freaking me out!!! Her first friend there was a Hispanic emo girl who told her she needed a reduction and that one of the popular girls teased her on facebook about it. There was also a non-popular guy that hung out with them, and he stormed off once when a popular girl, who was being nice so that the guy she liked (who sorta liked the new girl) would be pleased, offered to buy them milkshakes or something. If you guys have any idea what this book might be, PLEASE tell me! This will bother me forever if I don't remember it. Thanks!

Looking forward to finding out what it is... lol ... I may want to read this.

Haha, I'm looking forward to finding out what the title is!! xD I remember it being a good book.... but it irks me that I don't even remember the mainline plot...

Oi.... xD I still have no lead on this book.... And no good search engine can figure out the side characters.... so that's a nono...
