This happened to me as well. Give your body time to heal. One person gave me the advice that "getting back to normal" may take as long as treatment was. I healed sooner than that, but it gave me mental strength to just give my body more time. I also had a hard time "forgetting " cancer after going through surgery, chemo and radiation. I am happy to say that after 1 and 1/2 years post treatment, I feel free of the negative weight cancer was in my life. So hang in there. Someday you too will be on the other side of this and you will look back at your strength and feel that you are stronger than ever.
