A big zchus for a person to get-any-kind of help they need from Hashem. Daven for someone ELSE who needs the same shidduch/child that you are waiting so long for. And the seforim say when you daven for someone else YOU get answered first.
May Hashem always answer your heartfelt tefillos right away. As we say 3 times a day karov Hashem…. Hashem is close to all who call out to him WHOLEHEARTEDLY (and not just reading from a siddur or tehillim)
