Hi Scooter,
Welcome to Webhealing.
I've personally never experienced the empty nest that you write about. I have three children but they are now in heaven. I do, however have friends who have gone through a difficult time when their kids went off to college or moved far from them. They keep in touch through Skype as often as they can and that really helps. You'll have to find what works for you and your family.
Let us know how you're doing and share what has worked for you. It helps others, too!
Hugs,
Terry
