Nancy, I can't tell you how much my heart goes out to you. My husband died when I was 57 really sudden. 2 years later I had colon cancer ..surgery, chemo and all that. When I went for my 10 year final checkup, I found out the colon cancer was still gone but I had lung cancer. They removed a lobe and hit a nerve and now I have a frozen diaphram and am on oxygen and the pulmonary doctors thinks its permanent.. I had surgery in Jan 2018. In March, my son (52 years old=only child) was diagnosed with stage iV pancreatic cancer. I now take care of him so his wife can work and I take him to chemo etc. Not much hope for recovery unless something new is discovered. I try to enjoy him while I can and accept life as it hits me but some days I am just overwhelmed. I am 70 now.
Its pretty hard to hide from other peoples sickness and often people just don't think. I try to go to the gym or at least walk every few days. I know it builds your immune system. Some days I just can't find the energy.
I have two adult granddaughters that I am very proud of and 5 siblings who try to help me as me as they can. I feel very thankful for those things. I live alone so it is always hardest when I think too much.
