Good luck to you with your treatment! The first day of my radiation (last December) I felt like such a failure because the breathing was hard for me. But I went home and found a video on breathing during radiation. A male doctor had produced it. It was very helpful. I think I practiced for thirty minutes or so. The ladies couldn't believe it the next day when I showed up and kicked that needle right up there (and hold). We are Warrior Women and we will succeed! But it is one day, one breath at a time.
