Dear Sherman,
I remember feeling this way at the end of my Masters thesis. I could not describe the feeling very well until the several years later when my father was dying a slow death from Alzheimer's disease. I was grieving in advance for what I was loosing and fearful of the future and its changes. While at the same time I was to rejoice at dad's healing in heaven. It is a strange mix of loss, relief, and joy.
I will pray for you in this time of change.

Russ
