She's in Labor...and I Can't Stop Crying

My younger sister went into labor this morning pretty early so by the end of the day we may have a baby.  She was due this coming Friday but a few days early is still pretty close.  I am praying that everything goes smoothly and I think I'm in need of some prayers myself.  Every time I stop to think about my new niece, I break down in tears. Dear God, please help me get through today.
