Thank you for your post @denise96. I am so sorry for your husband's disease, his pain and his anger at God. No doubt he is horrible pain. I( am praying for his pain and his salvation.
And @denise96 the caretaker hurts as much as the patient. You also are included in my prayers.
I pray God will bring you comfort and your husband ease of pain and a change of heart.

Thank you for the advice concerning my wife's chemo treatments. And thank for your prayers, They are greatly appreciated.
Take care of yourself and stay strong in faith.
