I agree that counseling will be helpful for you, Antonia. I remember how I used to not be able to sleep, my thoughts spiraling around the same issue, endlessly trying to figure out all the nuances and side roads it could take ... like a chess match, trying to foretell any future moves. I managed to get out of that when I had to focus on my health. Cancer has a way of doing that. I started meditating, eating healthier, taking my Vit. D3 (helps reduce tumors), finding humor in things, and so on. I sleep very well now, because I have faced my worse fear, and overcame it. Try not to get to that point before making the changes you need to make for a peaceful life.
I have started a new diet - http://caloriecount.about.com - where one can not only count your calories, but oversee what nutrients you are taking in. Very helpful when trying to get healthy, I think. I have been on this for 5 days, so early in the process, but it might be something you can try, or something similar? Just a thought. If you can manage your health is such a way, it might bring some peace to you.
As I said above, meditation works --- I even meditated while on the radiation table. I don't do it as much now, but it sure helped me through some tough times, as did prayer too.
Keep on keeping on. You will get through this.
