Am i anorexic......................…

I am a guy in my mid-teens, about 5'4 or 5" and 115 pounds. I was in a cooking cl and talking to a clmate about how much I love cheeses, such as the brown Norwegian goat cheese and the common pepper jack cheddar cheese. I told her that I would be rail thin if it weren't for cheese, and that all my chub was from cheese. she then proceeded to tell me that I must be kidding because I am rail thin. I know she wasn't flirting because we both have our own significant others and she's not exactly a complimentary person. This got me thinking because I usually have a very small breakfast, no lunch, and a moderate dinner with small snacks in between. I get a decent amount of exercise. whenever I look in a mirror all I see is a chubby porky version of myself. I know that I am at risk for diabetes so I try and go light on the meats and I've been noticing that I have been going light on food in general. Nobody has ever called me fat before. I get an average of 5 1/2 hours of sleep every night, going to bed around 10:00 getting up around 3:30-4:00. Is it possible for a guy to be anorexic? Am I anorexic?
