Hey Rocco, I am sorry for your loss. I held my mother as she died in a similar scenario a couple of years ago. You're right, nothing prepares you for that type of experience. It will stick with you, but you will grow stronger from it. Write your eulogy, and find the best way you can to say goodbye and to celebrate his life. For, as you say, he overcame his physical challenges to touch those around him, including you. That means his life was something to celebrate. You all will go through this, and you will grow from it. I will pray for your family.
