Well, thank you for answering. I take your last sentence to mean you would want to live in that circumstance whether or not you had "... a family that loved me an[d] took care of me" -- since that would be outside your control.
You went off at some length villainizing Michael, but I think you make too much of the personalities of the people surrounding her because of the positions they take on the issue you care so much about. The parents are greedy, grasping people also who wanted half of Michael's settlement and wanted to become Terri's heirs at law. If Michael had been wise enough to simply give them half the money (even though they had no right to it) there never would have been a lawsuit and Terri would have died 7 years earlier. Similarly, if there had never been a malpractice settlement, there never would have been a lawsuit and Terri would have died 7 years earlier. Neither side distinguished themselves in this matter -- Michael for his adulterous relationship and the parents for their brazen money-grubbing.
We are clearly different people. For me, it's not 'all about me.' If I were not conscious or if I were conscious, I would not want to be the dead weight on the family eating into time and money with no hope of recovery, cheapening everyone's understanding of the significance of life. Either way, I would want to be dead. A fortiori if I were conscious. What agony that would be! Knowing of the needless burden I was imposing on all around me. Time for exit stage left.
