Lagun, you're a good-looking guy. Your ears and eyebrows are fine. And you're NOT fat in the slightest. In fact, I would say you're still too thin. Listen to your friends, they are telling you the truth. If you put on some more weight, it will not only be healthier for you, but will also make you look less adolescent.
Are you seeing anyone about your anorexia? Might be good to have someone looking after you to make sure you're eating right.
Perhaps it's also time to work on your inside as well, and not be overly concerned with the outside?
