Oh Doodlebug - I'm so very sorry to hear the news of your Dad's illness. Please don't all fall apart!! Now is the time that your dad needs your family all close together & you need to all work through this together. Now more than ever. You sound like such a close-knit family and I applaud your strength for what you did by your Dad's side over the weekend.
I have your family & your Dad especially in my thoughts.
