Wow, you could have written this about my late husband. He died from non-smoker's lung cancer. He died with a mask on his face because his lungs had collapsed. It was a terrible, horrible thing. In his last days, what I remember most was the panic in his eyes. I still have nightmares, but for the most part my heart is healing nicely. At the time of his death our children were 7, 5 and 2. Now, 12, 9 and 7. Life goes on...I am remarried, a writer/blogger and doing well. You can read more at choosejoy.co if interested.
