I dare to suggest that you didn't have time to try other methods, did you? (:
First, I tried to show the patient how beautiful the world is and how wonderful it is to live. Then we drank tea, watched Might and Magic, and ate double chocolate cookies.
But when I realized that everything was hopeless... I used that very method.
The person will leave this world, but their family and loved ones will not blame themselves for their death, thinking that they died at the hands of a murderer.
Do good.
