I think this is a somewhat meloramatic article in tone, but that's to be expected I guess as it was written as a journalistic piece and by a man who's still in the shellshocked period that follows diagnosis. As has already been said, the family will gradually adjust to their new 'normal' and day to day things will not seem so bad.
From a personal perspective, I have to say I used to feel a bit 'stalked' after my older daughter was diagnosed, and was paranoid about the younger one developing it too. I didn't have to wait long, just over a year and then she was, so the stalked feeling went away, because we had been caught!!
It is true that every day, hour by hour, is invaded by Type 1, you can never take your eye off the ball, never have a holiday from it, never ignore it. It is quite tiring at times and immensely frustrating when you try hard and can't get things right, but as Jenny said, we manage.
I greatly admire you, Jenny, doing it all by yourself, and coming to terms with the future that you see for Khaleb and for yourself. I think you are a terrific example of how parents rise to the challenge of coping.
Best wishes,
Sue
