After the successful adoption, my aunt completely changed. All she ever wanted was a family and to raise children. Adopting their son from Korea inspired her again. She got off medication and returned to her fun, outgoing self. It was an amazing transformation. They wee both in their mid forties when they decided to adopt.
I'm so sorry for your lose, but please, don't get discouraged and give up on having a family. Consider adoption. There are so many different kinds of adoption available these days and there are so many children in need of good loving families like yours.
If you need more information, DM me and I can go in more detail about their experience.
There are options available for people that want to have a family, and god knows there are far to many children out there that can really, really use a loving parent or two.
As a father of two I may come off as smug here, but I can tell you that the first year of a child's life is more going through the motions. The following years are really where you can make a difference, and where they certainly make a difference in you.
I seriously hope once they are over their grief period, that couple takes your advice. A child out there could have his life changed forever because of it.
