OK .. I stand corrected
The lawyer for Terry's parents is on Gretta and she said that the story of bulemia was just a theory the doctors in 1990 came up with and that there was no proof of it.
Furthermore, if she had an eating disorder which is only speculative at this point because we haven't heard of any official diagnosis, she could have been committed and force fed, although treatments differ. I can pretty much guarantee that if she had deteriorated beyond a certain point, she would have been force fed and possibly committed by a court to have it done if not done voluntarily.
The bottom line is no matter what brought her to this point, it is immoral and inhumane to withhold food and water to hasten her death because she has become a burden to her husband.
And yes, it could be inhumane to keep her in this state indefinitely, in which case, AFTER EVERYTHING POSSIBLE HAD BEEN DONE TO REHABILITATE HER FAILED WHICH HAS NOT BEEN DONE, then I would hope that her life would end naturally and mercifully, with the aid of the feeding tube. Oh the irony.
