I just got home from my 17th radio, and I can so relate to your sudden feeling of loneliness. It often happens to me when I am having treatment, and for me it is because it brings home the fact that it wouldn't matter how many people you might have in the waiting room, or who is back home thinking of you, there are some things that you have to go through by yourself. And when you are the only one experiencing it, it is very hard to describe it to someone else. Some times it makes me feel very alone and sad, other times I get strength from saying I did it all by myself, and got through it. And aren't those weekends off treatment great! Jane
