IM 18, I workout, and try to eat right. I wear a size 10 sometimes a 12 it depends on the jeans and a L in tops.
Honesty please!

You didn't mention gender but Im going to assume you're a female. And that's how Im basing my answer.
For that height that is close to normal weight. If you work out then Im sure your aware that muscle carries more weight then fat in the body. So height and weight are important factors they don't always determine your you. For that you need a mirror. How do you feel about yourself? That's really the main thing. Retorical question.(do not answer) Can you wear almost anything you want or is there clothing you wouldn't wear because of how you look?

Everyone has their personal ideal weight and your true goal is to attain that weight which fits you best. That is the real "you" that you seek.

Do you think you are chubby? If not then no.
