What's worse than having to do a cost-effectiveness analysis?
Having to do one for a dying pet.
Having to face the fact that no amount of money will guarantee that he will live.
Having to face the fact that the treatment options may themselves kill him.
Having to face the fact that the treatment options will definitely diminish his quality of life.
Having to face the fact that very soon you will have to say goodbye to someone who has meant more to you in this life than most others have, and that your decisions are what will determine the specifics of this departure. Someone who has been the closest thing you and your husband have had together, for the past 6 years. Someone who, 1 year and 8 months ago was given (optimistically) 1 year to live by the surgeon who saved his life. Someone you can't imagine living without.
Having to do all of this today.
