I am constantly putting myself down because I don't think I'm good enough?

Hey, don't stress over this! Remember - nobody's perfect. It seems like you are trying so hard to be better than you think you are - that you don't see your potentials and your own beauty. Yeah, looks aren't everything. And yes, make-up is not going to solve anything. What will help you though is; to start realizing that you ARE beautiful, and you are kind, and you are a positive person, and etc. (all your positive factors basically:) Beauty is in the eye of the beholder, so the faster you realize that you are beautiful, in your own unique way (as all people are), the faster other people will see it. Good luck!
