Conflict Of my Book

So far in the book "The Earth, My Butt, and Other Big Round Things",
the conflict is person vs. self. The problem is with the main character Virginia, who has issues with her body type. She calls it being "fat" and follows the "Fat Girl Code of Conduct"; which she made up. For right now, her and her "guy friend" are having issues about each others bodies. This is a person vs. person conflict. I predict that they might need to make some serious decision's.
