Should I change myself?

I know beauty is skin deep and all that, but whenever I go out of the house, I always feel that everyone is prettier than me. My closest friends look beautiful without even trying.
I'm sick and tired of always retaking photos again and again because of my face, and of people subconsciously agreeing with me when I ask them, "Do you think I'm ugly?"
I could go for a makeover, but I'm afraid I will lose my individuality along the way. What should I do?
