jealousy jealousy

I fucking hate how jealous i am of my friend but i just cant control it. I was all i fine until recently she got all prettier and more popular, the thing that bothers me the most is that she knows im jealous of her, yesterday i couldn't stand her just taking picture all dressed up and pretty while i didnt feel confident enough and just sat there on the bed, so i just said i was gonna leave but she knew something was wrong and we started a stupid argument and i accidentally spit out of how jealous i am and started crying like a baby, i mean i think i have a right to be atleast a little mad at her cause we were talking about something and she kept on judging me about my body giving me dirty looks and stuff and talking about her stupid likes and her stupid date and how she loves her other friends so much i just cant stand it.
