Jeff, I know what you are going through and how difficult it is. I'm the oldest child, too, and my father died from esophageal cancer two years ago. I lost my dad and my hero all in one, and my kids lost a grandfather. I know how much your dad means to you and he knows how you feel. You have been a good and loving son, the best he could have ever hoped for. He's proud of you, so proud of you that words can't describe. Your mere presence is all he wants at this point. Stay with him as long as you can. Believe me, he knows you love him. Feel free to tell him anything and everything, tell him you love him (I didn't say "I love you Dad" enough when my dad was healthy, so I was not about to let the opportunity slip while he was ill). Reassure him that you'll be there to take care of the family. Hold his hand. Be as strong as you can. Your friends and family will be your crutches. Use us. We feel for you. Our prayers are with you Jeff.
