Tim Worstall articulates my concern about this case very well. That doctors should let a depressed woman die for fear of being struck off if they contradicted her "living will" is appalling. A physically healthy 26 year old who chooses to die is, by definition, unfit to make a rational decision to do so.
If Tim is weird about this, so am I. This young woman was perfectly able to administer the fatal poison herself. She summoned an ambulance and put others in this horrible moral dilemma only because "she did not want to die alone and in pain."
So which is it? Was she was mentally-ill and legally-incapable of making her choices or was she a selfish coward?
