Rose,
So sorry to hear about your mom.
My mom will be 90 in December, and I already try to steel myself for the day she gets ill.
Well, your son sounds like he wants to be out experiencing the real world, good for him. Amazing he can afford it, just being 19. I had a little itty bitty case of the empty nest syndrome, but I sure lost it quick and enjoyed the peace and quiet.
Hugs to you Rose....
