Just now I have this voice in my head saying these words:
"My hope doesn't lie in the thought/belief that I will have my own children someday. My hope lies in the knowledge and belief that He will sustain me no matter what. His grace is sufficient and it is beyond understanding. My hope lies in the knowledge that He cares and He knows my feelings and He can and has healed my bleeding wounds and if there are other bleeding wounds in the future, He can and will heal them."
And that is enough for me, even if no kid will ever be my own.
