You could read Luke 1, and pay particular attention to Zechariah, the father of John the Baptist.
In Luke 1:7 it says that not only was Elizabeth, Zechariah's wife, not only was she barren, but that they were both old. And yet, in Luke 1:13, while Zechariah was on priest duty in the temple, the angel Gabriel showed up and told Zechariah that his prayer for a child had been heard. Gabriel is a messenger who stands in God's presence, and it seems that whenever he appears, it's to bring good news.
What you can glean from that is, Zechariah was an old man. He'd probably been praying for a child for decades. Gabriel gold Zechariah that he would have a son, and this son would bring him joy. This child would not be just any child, this boy would be the one who goes out to prepare the way for the imminent coming of the Messiah!
If you desire this in your purest heart of hearts, and you kneel before God every single day and pour your heart out to him about this desire, well, in Luke 11:11-13 says "What father among you, if his son asks for a fish, will instead of a fish give him a serpent; or if he asks for an egg, will give him a scorpion? ...how much more will the heavenly Father give the Holy Spirit to those who ask him!"
I'm retired, I'm more than twice your age. Trust me, God is more loving and merciful and kind and gentle than you could ever imagine, and if you live to be 100, you will still discover that God is more loving than you could ever imagine. I retired early due to heart issues. I was in the hospital and thought I was going to die (I'm actually not supposed to be alive still, several times over).
The chaplain told me something that left me dumbfounded and speechless in awe. He told me that however long I imagine eternity to be, at the end of eternity, I will still know less than a drop in the ocean about God. He said that God is so infinite and eternal and vast that we will never, in all of eternity, reach the end of Him. With the veil pulled back, with the ability to fully know God and stand directly in His presence... with absolutely no barriers, we still will never reach the end of God, and His love. In eternity His boundless love will only grow more and more, and our understanding of His love will only grow more and more.
That's mind blowing.
And also, maybe that Person, maybe He is gently nudging you. Maybe He's nudging you to follow that heart desire. Who do you think caused your purest heart to desire what it does? Or maybe He's going to surprise you with something better than you are currently able to grasp or understand!
What if there's something better around the corner! The God of Luke 11:11 is like that. He's not capricious or vindictive or punitive. He's not mean.
Maybe you dig a little bit deeper, and see where this leads.
