thanks i will bear those ideas in mind, it was helpful :)
A couple of possibilities. One, when you changed your diet, you stopped eating something or things you were allergic or intolerant to, and now you're adding them back in and your body is rejecting them. Modern humans force a lot of non-food into their bodies, such as dairy and wheat, that were invented by humans and many of us don't realize until we're older and develop arthritis or auto-immune disorders that we were force-feeding toxic food to ourselves. Another possibility, given your age, is psychological -- girls your age can become extremely body shape sensitive, and while it appears you did this in a very smart way, there could still be some psychological stuff coming out. That's how so many young girls and models and actresses develop anorexia and bulimia. Have no idea if that's what's going on, but just suggesting the possibility. Doesn't sound like it from your description, but there it is.
