How can I boost my self esteem?

People tell me I'm pretty and I'm skinny and i have pretty curves adn all of this but i think opposite. I have a boyfriend, but he actually never says that I'm pretty, only my friends say that. He likes my body, sure, but I don't really think I am good enough for him. He is a skinny and hawt (in my eyes) mexican and I am just a white cracker. I am pale and I just don't find myself attractive. I constantly am at work (waitress), or volunteering at places, or helping a friend. I just think I am just not very attractive at all. I also got facebook if you want to see. April Waldner
