Sorry for all your dad is going through. I'm familiar with this. First my Mom with cancer. More recently, my dad and all that comes with aging (he is 83) and his heart condition and diabetes.
It is hard to see our parents in a weakened state. It is hard to change roles. But our parents were very good to us and they deserve the best in their later days.
I visit my dad whenever I'm home, take him to his appts and go for dinner. He is the world to me, just as I'm sure your dad is.
I will pray for your dad and for you. I hope this difficult stage passes quickly and he is doing better very soon.
