Seeing people from the past

Now all you ladies are really going to think I am nuts if you don't already. I am 36 yrs. old, in outside sales, married with no children. Cancer struck when I was 31 yrs. of age. This is a very painful subject both my cancer and children. That being said I find that when I run into people from my past I always duck them. I really do not want to hear all of their great "updates". I rarely share my situation with just aquaintances. At business meeting share their pictures of their newborns and I smile and I am gracious. It kills me inside that this is my life and that my husband and I have been so cheated. Can any of you relate to this?
