It is best to be completely open and honest when you approach God.
Read: Isaiah 38:3-6
3 “Remember, O Lord, how I have always been faithful to you and have served you single-mindedly, always doing what pleases you.” Then he broke down and wept bitterly.
4 Then this message came to Isaiah from the Lord: 5 “Go back to Hezekiah and tell him, ‘This is what the Lord, the God of your ancestor David, says: I have heard your prayer and seen your tears. I will add fifteen years to your life, 6 and I will rescue you and this city from the king of Assyria. Yes, I will defend this city.
