Dealing with pregnancy loss while friends announce pregnancies.

I gave birth to my baby boy Kingston Jamal Cunningham on 4/19. I was 19 weeks, so he died after and hour and a half because the hospital refused to help because he was "too early"! Now it seems like everyday another friend is announcing their pregnancies, and I really want to be happy for them, but it still hurts! Has anyone else been through this? How did you cope?
