A fight with myself...in my head...wtf?

You might just be depressed. It's easy to question your looks and self esteem when you're depressed. But from your picture, you look very pretty. You have to remember that it's all in your mind and you're just putting yourself down for no reason. Plus, you're a teen. Not a single teen (including myself) thinks that they are perfect many go to school and always worry about their thighs or their hair or something else about their physical appearance. So try not to be so hard on yourself because what you're saying isn't true. You are very pretty. :)
