Six Months Old!

I can't believe my Abbie is now 6 months old!! She is sooooo big! She weighs 21 lbs!!!! The foster mom asked me if I wanted to see Abbie. They will be coming through this way on Aug. 8th. I don't know what to do. My heart begs to see her! But can I handle her not knowing me? When I put my arms out to her and she turns away, can my heart handle that? Will it break? I just don't know! God, please show me what to do!
