@mcleslie- Oh it's great that you answered back! First about the fatigue. Unfortunately, it's the name of the game. Lung cancer takes up room in your lunges and gives you less oxygen to use on top of that radiation and chemo will make him very very tired. That will change as he gets through them. Living cancer every day could very well be your lives for a while. Cancer will stay with your husband as he will be looking over his shoulder to see if it returns, gets worse or is cured. For now, because of his on going treatment it is your lives, but you know that. As time goes by activities will be more of your focus than the illness itself.
I am so glad that the Vet is taking good care of you. Being on one income is tough but it looks as if you are on top of things for nowe link:.
Would you be interested in our caregiver's group? You have a very tough job that requires a lot of patience and love. It's tiring and stressful and you will need support from people who know how you feel and have been "there" Here is the link: https://connect.mayoclinic.org/group/caregivers/
I know that your husband is very tired. Might you ask him if would like to join this conversation himself?
