Welcome to the forum. I am sorry you have to join our circle of friends, but on this forum you will find that there are a lot of knowledgeable members and everyone is supportive.

It is important to stay positive as this will make the cancer journey easier for you. Also, it may help if you try to take one day at a time. When my husband was in treatment, I learned to not worry about the outcome of a CT scan or a consultation with a doctor until I was actually in the consultation room. I think that helped me to roll with the punches.

It is likely that radiation will cause your thyroid to go even lower, but, really, as you already know, it's only taking a thyroid supplement a day. In the meantime, you may want to go out and eat everything that you love eating since surgery and radiation will mean that it will be a while before you can find enjoyment in food once you start treatment.

Glad to know you plan to be a regular visitor. We will certainly want to hear how you're coping from time to time. I'm sure ChristineB will be along shortly to tell you about hydration and nutrition, so I will leave that up to her.
