This is a hypothetical question., but all the same deserves an answer. I would spend the last year travelling all over the world and telling people about the Gita, the song divine of the Lord Krishna.
I would bring the fact that the soul is immortal and does not die away and will appear again in another body in another galaxy. so have no fear of the inevitable and trust in God and the Lord Krishna for life and death are but a milestone on the path to mukti( salvation).
The message of the Gita was told to Arjuna the Pandva prince before the onset of the battle of Kurukshetra. The lord touched all aspects of life and death and said the main aim of the human soul is to be one with the Lord himself
