crippled with fear

As I near my transfer day (tommorrow or Sunday). I am now completely scared of the possible outcome considering everything I've been through. This cycle has been very positive and went smoothly. How do I get past the fear of this happening again?? I have drawn on the strength of God and saw how brave you ladies are to get back up and try again. I am completely scared now that I will never see the face of a living child that is my own.
