Well, there are two days that I have felt the worse I have ever felt. First one was at the age of 11, watching my mother as cancer slowly drained her life. Seeing her feet swollen. Having her look me in the eye, and tell me that she is going to the hospital for a few days becuase she does not feel well. Two days later, my Grandmother told me that she had passed away.
The second, I was 19 years old, and went in to see if my Grandma was ok, only to see her lifeless in bed. Sometimes to this day, I still have that image in my mind.
