I agree. The issue, as you stated from the onset, is that you lack confidence. And you seem to want to torture yourself further by comparing personal features you don't have with idealized versions of those that do (high cheekbones? So what).
So drop the self flagellation & make something of your own talents. You will find your confidence levels suddenly change for the better.
