What folks said to me at this juncture that helped me keep some perspective: "You can do anything for 24 hours." So I did. I shut up, put on my serene face, detached as much as possible, approached the division of stuff with pragmatism, and tried not to be emotional and dramatic. Then it was over, and it was over. I did it.
So, you can do this for 24 hours. The light is at the end of the tunnel, and it is NOT a train!
