Hi,
I'm so sorry that your husband has lung cancer and that you are also having such a hard time caring for him. My husband had lung cancer also and sometimes he was difficult to care for. Your husband is frightened due to his cancer. I know my husband was too. Men often don't like to admit that they are scared so they react in other ways; sometimes not such pleasant ones. It's hard but hold your anger back. He's dealing with enough problems right now. You are the best care giver for your husband! You are his wife who loves him and married him. Show your husband how much you love him. Tell him that often. I know I did with my husband and it helped a lot. I'm so glad I told him often how much I loved him because he died in 2024 and I can't tell him that now.
Another thing that helps immensely is to take all your problems to God. Just talk to him like he's your best friend and he is. God knows what you are both going through and he'll be there for you. My husband and I prayed together everyday and also read the Bible together. It helped us to get through an awful time!
I will say a prayer for both of you. I wish you both the best.
