Yeah, I'm really sorry for all the family-related issues people are having right now...

Vector, you know you're awesome, and entirely deserving of love, respect, and admiration. There's that old adage, "Margaritas ante porkos," about offering valuables to livestock. Pigs don't see the value people place on pearls; their barnyard world comes with a different set of concerns and values. Though a bowl of cheep corn slop would probably go over splendidly, if all you find yourself with are pearls, just content yourself with their disdain and save them for some other time.
To ditch the allegory for a second, not everyone will appreciate things of worth and beauty. This isn't to say your family aren't also good people worthy of love and respect, nor to say that they don't care about you... they're just stupid sometimes for not seeing what an awesome, capable, and talented person you are. Don't let their shortcomings get you down and just keep on rocking, okay?

The same applies for you, Truean... though I'd add that there's a lot more going on in your life than your job. I'd bet you're not aware of half the ways in which you've made and continue to make the world around you a better place. You've got a great sense of right and wrong, an admirable attitude toward helping others, and treat your life and your actions with a gravitas that few do. Stick to your principles, and continue to do what's right; you're a rare breed.
My grandmother is now almost completely gone. She isn't capable of saying anything at all other than "that's right","I love you" and "I am ready" (ready to die). The only physical movement she is capable of is opening one eye, pointing and eating (barely).
I don't know what your relationship is with your grandmother, but if it's anything like the one I have with my grandfather, I can begin to understand what you're going through. She said it all already; send her your love, and know that she'll always live on in you. Life's like that.
