Okay, so this started happening a while back. Almost every single time I eat, I get sick...  My dad said it could be a lack of vegetables.  I never eat vegetables...  Instead of veggies, I eat fruit.  The only veggie I eat is the potato.  Sometimes I go a day without eating, and the next day, I eat a lot and get extremely sick. This happens when I don't eat a lot as well.  So, could anyone tell me what's wrong?
