What to do? Family Problems

When I decided to start this blog, I decided that I would strive to be 100% honest and that it reflect how I am feeling at the moment of each entry. Bearing this in mind....

NOTE: If you are related to me, proceed at your own risk

You ever have one of those days where you seem to be going along pretty good and then *bam* you get hit between the eyes with stress? I had a pretty busy day at work, slinging books to the masses and then I get home and between talking to my sister and my mother, I now have stress big time. Not because they gave me that stress; it's the news they gave me about my uncle.
My uncle is not long for this world. Mind you, he's helping himself along that path, but I came to find out today that my cousin (his daughter, the Ingrate) is not helping at all. My Uncle Jay (not his real name) and his daughter have, to the best of my knowledge, had a strained relationship. However, let me put this to you: how cold of a human being is she to tell my mother that when her father died that someone let her know so that she could get his money? Not "so I may have my final moment with him", just to get his money (not that he has any.) Mind you, Ingrate's not doing one single thing to care for her father - oh no, she's leaving that to my mother, since my uncle's other sister (my Aunt Linda - again, not her real name) doesn't seem to want to lift a finger to help in any way.
This man is my godfather. He stood with me at my Confirmation as my sponsor. I wish I could do more for him and for my parents, but I can't, I'm over 1300 miles away. Now, my mother is caring for her brother, watching him die and I am so afraid that she'll blame herself when he passes away.
Does anyone out there know what I mean? My wife and I sent out a great deal of information regarding care my uncle can receive from the Veteran's Administration to my folks (who aren't trained as caregivers and are feeling the strain), but I can't help but feel like there is more that I can do, or should be doing.
