Invasive ductal carcinoma, Stage 1, no lymph nodes involved.

Right mastactomy done 8/7/2013 and did receive 4 doses of chemotherapy. Started on Arimedex in january 2014. I was not able to tolerate this medication. Intense bone pain, I was not able to put my glasses on due to the pain in my nose and ears. Then the oncologist changed to Aromasin. 1 and half years after the aromasin, I feel very tired, sleepy, no energy, and feel like I am dragging my body. The oncologist asked me stop the medication for 3 weeks and the restart. I feel much less side effects now. I am able to tolerate the medication now. I do not know why. The doctor says it happens to some people. I have to be on this medication for 5 years. I also did have my left breast removed last week. I am so scared because of my mother's breast cancer that she had on the left breast. That is what I would think all day! I feel sane and relieved now that is gone too. I am 58 years old and still debating for reconstruction. i do not have use of my breasts and I also did not want to go through additional procedures, I did not go through the breast reconstruction. I do not know why, I feel at peace! I do not feel like that is important to me anymore. learning to live with my body and my choices. I feel a kind of free and liberated! Is this insane?
