Have you told your friend how difficult it is for you to hear about pregnancies and births? Maybe wait until you're having a better day and send her an email and tell her that you appreciate her friendship at this sad time in your life but you need to not hear about other people's babies for a while? After my loss I had some people in my life who were great and really seemed to understand what I needed, and some others that I just had to tell to back off, or to please not give me any more news of babies. Some people are just totally clueless and have to be told. Most people have good intentions, and your friend probably does too. But unless they have suffered a loss, they have no way of understanding what you're going through.
Some days you just have to wallow and hope for a better day tomorrow!
