Hi Mary,
I can understand how you are feeling at the moment. I am coming up to 4yrs since my breast cancer diagnosis. I am due for my Mammogram and Ultrasound this week, I am quietly confident that it will be "all clear".
Whilst undergoing treatment, you feel that you are taken an active part in defeating your cancer. All my determination was geared towards getting through treatment and then afterwoods I felt like I was set adrift. My time was free from the commitments of treatment. I asked my specialist what should I be doing now... he said "live your life", which sounds easy but I was a changed person and I was a little puzzled where to start. Then all the questions started appearing in my mind, what caused the cancer.. was it diet... was it stress.. was it environment. I was driving myself to distraction trying to find the answers, becoming more stressed. Personally, I had to let go of the question of "why" and now I am concentrating on recovering my enjoyment of life. Please know I am not telling you what to do, I am just describing what is working for me. We each have our own personal road to take.
I suggest allocating time for things you enjoyed before cancer, to regain your spirit. I went back to dancing...slower dancing than before... but music and movement lifted my spirit. Be aware of not pushing yourself and your body, listen to your body, you will know by the aches and pains whether you have been kind to yourself.
It is true, once you have gone thru cancer, your world and perspective changes. You will gain much insight and knowledge from this website, absorb the knowledge and make the choices appropriate for you.
I can't comment on your type of cancer as far as treatment is concerned, the other comments you received covered it very well.
I wish you a gentle journey and would be happy to hear of your progress along the way.
