Bad friend

Okay so, I'm writing this cus I cant hold it in anymore(I prolly sound cringe but whatever) okay so lately I've been feeling like a really really really bad friend, I js made a friend she's so pretty and I love her so much but I cant help but feel jealous. I posted her on my story and a guy I was attracted to was like "yo can I have her acc she's really pretty" my heart lwk shattered but I gave him her acc anyways and later someone else replied to that story and said "she's way more prettier than you" I was like "yeah I know she is". Im sick of being the "ugly friend" I love my friend so much but i can't help but envy her. I guess that makes me a bad friend.
