First, thank you all for your thoughtful kind words. I was having a really rough day handling it and wanted to put my feelings into words.
My dad has good days and bad days. He is still dependent on his oxygen, but about half the time he can get up on his own (with help from Mom or the nurse there to help put on his therapy shoes, he can not walk with out them). He actually got up and read his mail on the computer today! He will never be what he was, but each day we have him is a blessing, and my mom is enjoying each and every day she is blessed with him. Each morning we chat, and her first words are "he is still breathing so all is good".
I am blessed to have such a role model in my life. I will always remember that. For now, survival for me means not dwelling on the sadness of the situation, but remembering the good times and the knowledge he can still impart to me (he is an amazing cook, so I call him often for suggestions on new food stuff to try making).
Again, thank you. One day at a time, and comfort in my Savior's arms, helps me get by.
