I had to go through something a bit similar, but on a smaller scale, with my mom. She had lung cancer, then it developed into a brain tumor. When she was unable to eat on her own anymore, my brother and I, along with her physician decided that we must honor her wishes, and follow the advanced directive she had signed, which stated that she would not have any life sustaining measures, which included iv's or tube feeding. It was excruciating for me to watch her starve and be without water. There were a few times she regained consciousness and asked me for a drink of water, which I attempted to give her. She was unable to swallow properly due to the brain tumor cause her to be paralyzed on her left side. I feel for Terri's family having to watch this, but also know that we have to honor our families wishes when they have stated them.
