confidence issues

I've been feeling really self conscious lately and it really is weighing down on me. I'm usually one of those people who can fake it till I make it with confidence but at the moment I can't even do that. it sucks because I'm surrounded by beautiful people and all my friends are GORGEOUS and then there's just me. Even when I do try to look good it never works! and boys don't really give me attention (and yes I know I know "boys are dumb, don't base your worth on boys, etc.) but still, why don't they like me or give me attention that they do to my friends? what's wrong with me ? I don’t even have the confidence really to put myself out there because I fear rejection. all I really want is to be confident in myself and love myself like I know I can and should!
