I went through this pain. By far the toughest thing I had gone through in my life. After seven years, B”H we were blessed with a healthy boy. While visiting a gadol in EY asking for a bracha, he said something like this:
1) H” can get you out of this situation
2) Understand that this is for your own benefit
3) Try to be happy as much as you can
There is no doubt that going through that period of time made me a better person and a better jew.
