Always someone else

Got a call today that my younger cousin is pregnant. After 4 losses I just can't be happy for anyone. She wasn't even sure he wanted kids. I also have a sister in law pregnant with #2 and again I love being an Aunt and wouldn't trade it but just someone else who isn't me. We have no living children and it just hurts all the time. I know it's going to happen but doesn't mean I have to jump for joy when someone announces they get the miracle I wish for everyday.
