Is Beauty Irrelevant?

I wish beauty was irrelevant. When I was a kid, I didn't think much about my looks and didn't care. I wish I could be like that again. Now, I'm going on diets, not eating, turning down the foods that I love. I am so miserable. If people didn't judge others, I wouldn't have this problem. I am always surrounded by people that make you feel like you won't be successful or be anything you want to be.

I honestly don't care how other people look. It is their business. Why am I the only one who doesn't care what people look like? I wish I could be myself and not care about the criticism. Hopefully, in a couple years, I will reach the point when I don't care what other people think about me or my appearance, and I will do what I feel like doing. For now, I feel fat, ugly, and useless. Hopefully that will change.

Is beauty irrelevant? Do you not care what people think about you? How do you not care? Please tell me, so I can learn to not care either.
