barfing CAN mess up lots of other things besides getting "fat".
i beleive i saw ur pic (while back)and i dont think ur fat (honestly)
i hear something like barfing ur food out after you eat could make u gain weight? soemthing like that. plus throwing up isnt a great feeling. i threw up earlier and it was so horrible.
just after u eat try and calm down and not think about binging (word..?)
