I try to imagine what I would feel like if the doctor told me that I would die within the next few weeks. The best way to find this out is probably to delve into your own experiences, looking for something with a similar impact, and how you dealt with it in the past?
When your car breaks down after you hit something in the middle of the night. When the apple was rotten, and you needed it for that recipe. When your lover cheated on you, or your grandmother died. In all these cases you were probably shocked at first, out of breath, felt helpless, or empty. If you have been through these experiences several times you might power on immediately after the initial shock, and if it is your first time it could slow you down to a standstill, unable to think or act. But can you compare the loss of a lover or death of a friend with the message that you soon are going to die?
