I don't eat often. Its 9 14pm and I've had a sub. I don't starve myself. I am just never hungry. Can I be anorexic and just not know it?

If you're not doing it on purpose, it's not anorexia. See your doctor to make sure you're getting the nutrition you need and if not, why you don't feel hungry. Perhaps it's something you're doing or perhaps there's a medical condition to explain it.
