You probably didn't want all this attention when Mac did what he did, but let me just tell you, you're beautiful. It's not fair of your mom to tell you that you need to be more beautiful, because you really can't be. You're just you, and you have your own style that some guy is going to love to death. You don't have to be one of those fake, plastic supermodels that everyone wants you to be. Look into the mirror with confidence because good looks are just one of the many things you've been blessed with. I really don't care what anyone else says, it broke my heart when I saw you telling yourself otherwise.
Believe me, I've been there. I hated myself. I refused to look in mirrors, and whenever someone said to write down all the things you like about yourself, the list seldom got a second item. I'm not asking you to all of a sudden pull a 180, but please don't put yourself down like that. Trust me, you'll feel a lot better about yourself in the future. It's just a dark road in the meantime, but once you get out of it, you'll realize just how beautiful you really are.
