Thousands... Millions...Children needing homes

On saturday, I spent hrs looking and wading through waiting children list from China.  And your heart gets heavier and heavier.  Can't sleep without these children marching through my dreams and becoming personal in my mental life.  I want to be in China now.. but yet I wait.  I feel like someone is standing on me and I can't get my breath.  I pray for them all and especially for my girl.  How do I know which one is mine, Lord?  Please guide my heart and speak to me!
