Every emotion you experience is represented in the Psalms.  Psalm 55 displays a number of them.  Have you ever wondered how to pray when you can’t pray, but can only groan?  Paul has some good answers for that in Romans, but 1000ish years before he wrote that letter Psalm 55 gives a good model (which is often more helpful than an answer, especially as it relates to Answering God).  Are you ever restless?  Same thing.  I love the Psalms.  Peter liked this one too; quoted it, with even stronger wording thanks to his friendship with the Man.

Give ear to my prayer, O God,
and hide not yourself from my plea for mercy!
Attend to me, and answer me;
I am restless in my complaint and I moan,
because of the noise of the enemy,
because of the oppression of the wicked.
For they drop trouble upon me,
and in anger they bear a grudge against me.
My heart is in anguish within me;
the terrors of death have fallen upon me.
Fear and trembling come upon me,
and horror overwhelms me.
And I say, “Oh, that I had wings like a dove!
I would fly away and be at rest;
yes, I would wander far away;
I would lodge in the wilderness; Selah
I would hurry to find a shelter
from the raging wind and tempest.”
Destroy, O Lord, divide their tongues;
for I see violence and strife in the city.
Day and night they go around it
on its walls,
and iniquity and trouble are within it;
ruin is in its midst;
oppression and fraud
do not depart from its marketplace.
For it is not an enemy who taunts me—
then I could bear it;
it is not an adversary who deals insolently with me—
then I could hide from him.
But it is you, a man, my equal,
my companion, my familiar friend.
We used to take sweet counsel together;
within God’s house we walked in the throng.
Let death steal over them;
let them go down to Sheol alive;
for evil is in their dwelling place and in their heart.
But I call to God,
and the LORD will save me.
Evening and morning and at noon
I utter my complaint and moan,
and he hears my voice.
He redeems my soul in safety
from the battle that I wage,
for many are arrayed against me.
God will give ear and humble them,
he who is enthroned from of old, Selah
because they do not change
and do not fear God.
My companion stretched out his hand against his friends;
he violated his covenant.
His speech was smooth as butter,
yet war was in his heart;
his words were softer than oil,
yet they were drawn swords.
Cast your burden on the LORD,
and he will sustain you;
he will never permit
the righteous to be moved.
But you, O God, will cast them down
into the pit of destruction;
men of blood and treachery
shall not live out half their days.
But I will trust in you.
(Psalm 55 ESV)
