Family pregnancies

Hey all,

I have been trying to concieve for 6 months now. We have had 2 miscarriages this year. We recently just got the go ahead to try again and I've been feeling insanely positive. Until last night when my husbands brother told us his GF is pregnant. The relationship is so new we have never even met her. It was completely unplanned and she already has 3 kids with a previous man. I can't even feel happy for them. I just cry and cry when I think about it. It feels so unfair! How do you be happy and discuss other's happy news without breaking down because you are living day to day focusing on your own fertility battle?!
