I share my experience in the hope that it may help others in similar circumstances. In Chinese medicine, the winter season symbolizes unknowing. Yet staying in unknowing, just sticking with the facts, is a way of avoiding unnecessary suffering. It is also a way of remaining calm. Calmness gives strength.
Strength is needed to face the unknown.
These words were a call to remain in the calm of unknowing. I sunburn easily, and I worried that my skin would be covered in blisters due to the radiation treatment. Then I remembered that I knew very little about the treatment. I could only speculate. Until I had facts, I determined that I would focus on today and how I felt today.
