It is a way of shrinking back, of reserving, preserving the self, fighting free of sexual and emotional entanglements. It says, like Christ, noli me tangere. Touch me not and take yourself off. For a year or two, it may be a valid strategy; to be greensick, to be out of the game; to die just a little; to nourish the inner being while starving the outer being; to buy time. Most anorexics do recover, after all. Anorexia can be an accommodation, a strategy for survival.
