You have some aspects of anorexia.

although i read (not that it is definetly true) that you can be diagnosed with anorexia which is wanting to be thin or what people may refer to as a "wannarexic" or a "wanna-bexic" etc... but anorexia nervosa is to do with the mind... im not sure...
but i think you may well just be classed as a fussy eater
