My aunt went through the same situation. She became clinically depressed for several years after going through the IVF process several times. She was on medication and had completely withdrawn from life. It wasn't until they decided instead to adopt a child from Korea that she changed, almost overnight.
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.
