Welcome to the site Decimaldancer. I hope that terry gets to read your post, but we don't know for sure whether he reads the site.
I'm so sorry for your loss - although there's a great deal of dignity with the way your father chose to go and although I'm sure you'll all miss him, I also suspect you are thankful that he's no longer suffering. He went the way he wanted to go - and that has to be a good thing.
Best wishes to you and yours,
Look, you've got it all wrong! You don't NEED to follow ME, You don't NEED to follow ANYBODY! You've got to think for your selves! You're ALL individuals!
Yes! We're all individuals!
