I DON'T STARVE MYSELF!! Why doesn't my family believe me?

I understand you completly. Seriously, they won't listen to you. I suggust just ignoring them, some people are really hard headed and just won't listen. You don't need to pack on any extra wieght, your just fine. If they really start pissing you off, you can show them that your BMI is perfectly healthy for your age and if they still bug you, next time you go to the docter, get a physical and have one o fyour parents present so they can see that you're perfectly healthy.
