While Drugs may help some, I had this song I chose in my head ( a song very close to my heart) and I started mentally singing it at the sound of the start of the radiation machine. I knew just how far I would get in the song and that was the end of the days radiation...Time passed quickly during treatments with that song and I buried the treatments in the back of my mind but the song lives on daily....as an old reminder that I am still here and kicking 7 yrs later...
