You nailed this feeling -

"I find it funny that people tell you to pray
And then when it goes wrong they say oh well
They say this is the way He intended it to be
And that you shouldn't dwell."

It's the go to excuse of why the promise of help from prayer 'didn't work'. It is such hollow, empty comfort to replace the belief you gave your heart to, that God was going to answer you. Losing that sense of belief really can shatter everything.
