I agree with Chrisy. Breathe !!!!!!!!
I know nothing about radiation, but I would say to make sure you get your concerns addressed and your questions answered before you start the actual radiation. Tomorrow might be a good time to do that.
Take very good care of yourself during the radiation.
Pamper yourself whenever you can.
You deserve it !!!
Keeping my fingers crossed for your and a hug goes out to you from me.
