I don't have any advise for you. All I can do is pass on something that was told to me by our priest.
We were having a hard time and it seemed that no end was ever going to come. We spoke with our priest one day about it. He said to have patience. That right now it seems like nothing is happening and that you are never going to bring that child home. However, in the big picture and as years pass with your child you will look back and hardly remember this little bump in the road. Good things come to those who wait.
In our case we spent a year and a half going thru one problem after another. Within a month of speaking to the priest everything started happening. Now we are out of PGN and almost there.
I hope this helps a little.
