Chilled to the Bone -- what does it mean?

Each year it seems that the three weeks of cookie season is colder than the one before. While I know this cannot possibly be true I also know that tonight was certainly one of the worst I have survived. When the evening's sales were at an end and I returned home my feet and hands hurt so badly I cried. I am not one to succumb to pain easily but I couldn't seem to stem those tears. My teeth chattered, my legs shook and my tears flowed down my cheeks. For the first time (ever?) it occured to me that I understood the phrase chilled to the bone. But as I pondered the idea further I realized that nothing about my life is chilled. I am blessed in every possible way. I have a family whom I love and who love me. I have friends whom I trust completely. I have faith and hope which buoy me even in my times of distress. I have medications and oxygen which allow me to follow my path in life despite illness. I have education, thought, and resources with which I learn. I have it all. So, can I really be that cold? I have decided that the only time I am truly chilled to the bone is when I lose my direction in life.
