I Feel Like the Ugly Friend

I've never had problems with my confidence and I've never found myself ugly. But recently when I'm hanging out with my friends, I feel like the ugly one. All my friends all have beautiful straight hair and I'm stuck with big curly hair. They're all tall and thin but I'm taller and muscular. I just feel like the odd one out. They all get attention from guys and I've never really had any. I like my smile but my face looks weird when I do smile and I just wanna be as confident as I was before. In the group picture I'm the second one from the left, and in the other I'm the one on the left.
