Donna,
My dad just finished up radiation to the right side at the end of August. Tomorrow he will start 7 weeks of radiation to the left side along with chemo once a week. We too were worried that they would tell us that radiation again, especially this soon, was not possible. We were relieved when they laid out the treatment plan.
Dad too is looking forward to starting his treatment tomorrow, mostly because you can see his tumor getting larger by the day, and his pain has increased to the point where he does nothing but medicate to control the pain. Hopefully the radiation will shrink the tumor and it will stop pressing on the nerves.
Your outlook is fantastic. No, it's not going to be easy, but I think you are going to get through this just fine with your strength and determination.
Best of luck to you and I will hold you close in my thoughts and prayers.
Joy
