however, the situation is a little bit fishy to me. if the woman is as capable as suggested, she ought to just kill herself, if she really wants to. it's a diagnosis from a distance, but it actually strikes me as a call for help, or perhaps for attention.
maybe this woman is of sound mind, but some other person in the same context might not be and the situation does suggest some deeper level of oversight is required. the doctors should be able to explain their decision to somebody on request.
