Sorry to hear that news Phil.
Remember, you're Mom needs your support regardless of her condition or decision of what she feels she can or wants to do.
I can't even imagine what she is going through, or you for that matter.
All you can do is be there for her and encourage her to do what she feels is best.
Thanks for the update. I've been wondering about her condition but I figured you'd let us know when you felt it was best.
