How do I not care that I am ugly?

I'm not very attractive and I realize people are going to bombard me with nasty comments on here (hey, at least i'm not ugly claiming to be beautiful like many on here) but I wish I wasn't so damn sensitive about it. Once people get to know me, I make fast friends but i hate that people are snobby in the beginning towards me. How do you earn respect from the get go if you're unattractive? I hate that I have to work harder at it. It also just brings down my self-esteem even farther and makes me not appreciate those relationships.
