ms shuttergirl - i am so sorry for the loss you and your family have experienced. it is horrid to lose someone you love at any time, however i know the struggles you have experienced and wish you all peace and happiness for the future.
my grandfather passed just before my 21st birthday and i got to spend a few hours with him before hand. the memories of being able to see him smile, his utter contentment at that moment and the feeling of his palm on mine as i got to hold his hand that last time bring me a huge deal of joy even 10 years later, knowing that he was happy in that moment. i know he truly is resting in peace and that is a memory i treasure and i know that your family will treasure their memories of those last conversations they had with him.
my thoughts and prayers are with you and yours.
