You will find someone! Guys are certainly behind girls as far as maturity goes in high school, even in the first few years of college, in my opinion. It seems like people in high school are more interested in what is currently desirable or cool, but when you graduate, most people (keyword: most) are more interested in what they want in a person.

You will find someone who appreciates your figure and personality. High school is only a blip on your timeline, and, chances are, you won't find the person for you until after you graduate. Don't lose hope, and be patient; love will come in good time!
