Answer:
Technically no, but some girls do get depressed because they feel that their not better or as prettier as them. Honestly, I've been down that road before and the only thing to help is to not think about it. I mean every girl is pretty in their own way. You just have to look inside of them instead of their outer apperances.
funny, NOO the ugly girls are jealous of the pretty girls because they get all the attention and all the guys drool over them not on them
and btw yeah you can say that beauty is only skin deep whatever but do you ugly girls out there want to be pretty or doo u wanna just say that beauty is only skin deep and that someday you will find love
goodluck
