Dragonfly, my friend, my children are still in the nest. LOL! But I want you to know we are all here for you when you need. :0)
This little piece of advice someone gave me when my first born got her first job and I was crying my eyes out might help you sometime......
She said "you are not letting go, you are simply turning a page. Starting a new chapter. She will still need you." Perfect words I needed to hear.
