so that girl used to go to my school and she has like 4000 friends on Facebook and her pictures get hundreds of likes. she is a really nice girl and always talks to everyone so everyone loves her blah blah blah. My friends will bring her up every now and then and say how pretty and sweet she is and I will say things like "she's average" "she's a bitch" or I will try to point out flaws. recently her and her bf broke up so now all of my guy friends are jumping at her. And as much as I act like I hate her I always look at her pictures and wish that I could look like her. I am just so jealous! how do I stop this jealousy/hate towards her!?!?
