Dear Marti, that is not stupid that is criminal! Family comes first in all matters, and Gods gift to children was their Grandparents! I too have moved many times and yet I have always been lucky enough in the end to find a garden, either my own or someone else's to help out on. I do so hope you get this sorted out, as who could be better than a grandma to look after a grandson. Don't worry, once a gardener always a gardener, and I am sure something will come up for you.
I really wish you all the best in your difficult times, but I know you can cope.
Regards from England.
Neil.
