I Am A 62 Year Old Female Who Had Chemo

I am a 62 year old female who had chemo for breast cancer in 1989. I was given 6 months to live. Here it is, 27 years later and now I have been diagnosed with congestive heart failure BECAUSE of the chemo I had. I have been staying in my low sodium diet, going to Phys Therapy for 4 months and have been taking Cardivilol and now Losartin. My heart function is 25%, down from 40% a few months ago. He said there is nothing more than can be done. Help? I want to live!
