Thanks everyone for your perspectives, it really means a lot. To explain, my dad is in the last stages of lung cancer, which metastasized into violent lesions across his head and neck, and now to other organs.
my issue is that he's always been the voice of reason and responsibility for me, he literally saved my life once, and this is my last chance to be there for him.
Everything that needs to be said has been said, but he is the kind of truly good person that they may not even make anymore, and he is just in so much pain.
