How do you deal with not being the best?

I have been clinically depressed for some amount of years now, but recently plunged further into the darkness with terrible feelings insecurity. I feel that I have to be the best looking person in the world or I am non-existent. I see great-looking celebrities with hundreds of thousands of fans waiting upon their every move, and the power and influence these people hold just from their appearance. I have been particularly scrutinizing pictures of Cristiano Ronaldo, whose symmetry is flawless, a true phenomenon that almost defies nature itself. I have obsessive compulsive tendencies which have erupted in magnitude when I find myself leafing through images of Ronaldo on the back pages of google images until 6 AM. Knowing that no aesthetic feature of mine could ever be better than his makes me feel quite worthless. I'm not even of orientation, but I can't stop marveling at such a precise masterpiece, it is like a good painting. I see all the love and attention he receives from people around the world, and here I am sitting by myself, lonely. I just wish I could touch so many people the way he can. My self-esteem is in the crevices of sedimentary layers of garbage at the bottom of a trash can. I suppose wanting to be the best at anything is an unhealthy obsession, but how do people deal with such feelings of inferiority?
