Sweety,
I remember at one point during treatment I was walking to use the bathroom and peered over towards the mirror. I was shocked that I didn't even recognize myself. From then on I used to hurry past the mirror and my wife kept asking why I was in such a hurry. She even started calling me Jar Jar Binks. My hair looked like a baby bird, thin and stringy looking. I had lost about 40 lbs then, soon to be 70. I couldn't eat, couldn't drink water without choking, couldn't move the bowels from the narcotics, was mean to everyone.
You are right, when you make it through the treatment...you can make it through just about anything in life.
