The psalms teach us to pray deeply and honestly without pretense or presumption. They just let it out and then let God sort it all out.
What if we did not judge or measure our prayers before we prayed them? What if we just let all of our negative junk out and laid it on the table before One who is wise, good, patient, loving, holy, and true and then .... well, then, we let that One deal with it.
"This stays; this goes; deal with this; I can handle this; don't worry about this; you might want to rethink this; I hear you. I understand I love you."
That is how the psalms sound to me. All the vengeful, angry feelings are brought before God before anyone else. All of the despondency we experience is brought to the front so that it can be addressed. All of our hopelessness and fear is exposed and God meets us where we are.
We see all of those heavy bricks of guilt and bitterness hanging on a cross and being demolished.
He knows we harbor hate in our hearts that is weighing us down. He knows that we struggle with temptation. He knows that we feel persecuted and alone. He knows and wants us to bring it to Him.
When we do, we are transformed as we are released from the power of those feelings. They only rule us when we cherish them in our hearts and guard them with all our might.
We may be afraid for people to know we are human, but it is useless to to try and hide that reality from God. He knows.
"Be gracious to me, O LORD, for I am in distress;
my eye is wasted from grief;
my soul and my body also.
For my life is spent with sorrow,
and my years with sighing;
my strength fails because of my iniquity,
and my bones waste away."
(Psalm 31:9-10 ESV)
