Do you think I'm anorexic?

Everyone tells me I am uber skinny... but I think I have a lot of fat to lose. I eat, but its not "right" i guess. I usually don't eat breakfast and I only eat lunch if people are watching me to make sure I do. And even then I eat very little. Like, a few cheese sticks. Just enough to get people off of my back. As far as dinner... same idea. I always eat dinner when my family does because my mom freaks out if I dont. Even then, I only eat enough to please them. But there are many days where I only eat a granola bar or something. I don't count calories or anything though... What do you think?
