Hi. I'm a 12 year old boy, and I only like to eat the same kind of food all the time for a week or so at a time. And I have to wonder, is this really unhealthy?

For a while it was poptarts with butter on them, and then ham sandwhiches, and then scrambled eggs with ketchup, and then waffles.
Right now it's mac and cheese. When I like one type of food, no other foods seem good to eat. My mom tries to get me to eat the food she cooks, and I eat it to make her happy, but then I feel like I'm going to throw up. I think my mom's boyfriend think it means I've got demons in me.


Is this unusual, and should I be worried?
