Here are so more wise words from Pope Francis which you may find encouraging:
“Without Jesus, our prayer risks being reduced to human effort, destined most of the time to failure. But He has taken on himself every cry, every groan, every jubilation, every supplication ... every human prayer. And let us not forget the Holy Spirit who prays in us; it is he who leads us to pray, he leads us to Jesus. He is the gift that the Father and the Son gave us to foster an encounter with God. And the Holy Spirit, when we pray, is the Holy Spirit who prays in our hearts.”
