Look at these verses on prayer in the Bible, God listens to every prayer.  Have this confidence that in every pray, whether it be small or large, whether it be well phrased, or just a bunch of broken words, God listens.  Sometimes what we think are the worst prayers, God just loves, since we are expressing our real feelings.

Psalms 66:19 But certainly God has heard me; He has attended to the voice of my prayer.

Psalms 66:20 Blessed be God, Who has not turned away my prayer, Nor His mercy from me!

James 5:16 Confess your trespasses to one another, and pray for one another, that you may be healed. The effective, fervent prayer of a righteous man avails much. 17 Elijah was a man with a nature like ours, and he prayed earnestly…

This  last verse in James eventually refers to Elijah who in a very unique situation needed a prayer to bring God in to vindicate Himself.   Elijah did pray and God did come in.

So never feel that God does not hear, He does hear and answer.   p.s.  answers do not always come how and when we expect them.
