How do you explain it to them?

How do you explain to your friends, who all have kids, that it just hurts you to see them with something you can't have?

How do you continue to plaster a smile all over your face when yet another one tells you they are pregnant with the biggest smile on their face?

How do I do it??? Not very well. I smile and ooh and awe and hold babies... And go home and cry in the silence of my room.  

They are a reward from him

Psalms 127:3 NLT

Children are a gift from the lord ; they are a reward from him.

Hearing this one is hard for me.  Each time a friend gets pregnant I'm happy for them.  Each post of a newborn baby wrapped in their momma's arm gets a hearty "like" from me on FB.  But I'd be a liar if I said it doesn't hurt to see.  

I haven't been able to have kids yet.  And so when I see that verse, it automatically makes me think I'm not good enough.  Haven't lived right enough (that's another story all together, b/c I KNOW I haven't).
