Kelly,
Not wanting to rain on your parade, I feel that I should caution you that things usually get worse for most people when radiation treatment ends, before they get better. I was never depressed until I started hanging around the house when radiaiton treatments ended. My voice, too got bad, but that returns soon enough. The radiation continues to cook you for a while after treatment ends and you don't have the daily support and interactive relationship with the health professionals like you do during treatment.
Hope for the best but be prepared that most of us here felt our worst in the first few weeks after radiation treatment ended.

Best of luck,

Danny G.
