How to overcome inferiority complex?

I always tend to think that I'm pretty and i look all that however, whenever i'm around my good friend (girl) I feel like guys would never notice me. #1 she's taller; #2 she's lighter in complexion #3 she has hips "to kill" (a really good looking pear shape); #4 she's super trendy and knows how to dress well and #5 she has a narrower and in my opinion cuter face.I feel as though no matter how i dress, I'd always look ugly once we're in the same room. How could i overcome this inferiority complex?
