I am very sorry, Mark (and I know that sorry, does not help, and I'm sorry about that also.)
I wish my own family appreciated the grim situation that you are in.
My family fights, and squabbles, and they waste precious time that could have been spent in family get-togethers, in celebrations, in holidays, in outings ... they sit and hate each other over petty things.
They seem to forget that life is a limited commodity, that what has happened to your mother IS going to catch up with them eventually, and when it does ... well, it will make all those petty squabbles seem ... they might just realize the stupidity of their behavior, in wasting their lives in anger and hatred, in bad behavior, but then it will be too late, and there will be no time to make up for what has been lost.
What could have been. What should have been, if they could have put aside jealousies and petty disputes and bad behavior.
But they will not learn, and that grim reality will come - as it has come to your mother - and they will realize they threw away something beautiful.
I hope that, in the time she has remaining, your mother - and all of you - can have the best of times, the best year of her life.
I hope you can.
Again, I am sorry, Mark. I know sorry does not help, but I am sorry.
