I am living with a terminally ill spouse. We discussed the options, researched the TREATMENT (not a cure), then discussed it all with our boys. We decided on no treatment why because the treatment could have killed him quicker, lessened the quality of life and we just couldn't see injecting anti-freeze into his body for 48 weeks as a good thing to do.
It is a personal choice. One that needs to be weighed out and prayed about.
God has sustained Dennis for 15 months longer than any of our health-care team expected.
Praying God's wisdom in this case.
