From a Grandmother with a similar problem

Pat Hanson

I am an Invisible Grandparent. I have two grandchildren that, I have been kept from seeing. Writing letters helped heal the hole in my heart that not being able to grandparent caused. In the last three years I have written dozens, in hopes that someday, these children who are part of my gene pool will read them. I have also written others I have no intention of ever sending in order to free myself of negative energy and work toward forgiveness of both myself and others.
