Amy, I am so so sorry for your loss. My husband died in September of 2020 from this horrible disease. He was 58 years old. Your post breaks my heart because it reminds me of what my children are going through. I can only say that your dad would be proud of you for worrying about him. Dads usually do the worrying. But he’s not in pain any more and that’s something to be thankful for. Cherish the memories and live your life to the fullest. That would make your dad happy. Wishing you and your family peace.
