Psalm 55 and Reed

Part of the homework for my Bible study is to read Psalm 55 and identify the four steps of "REED" as experienced by the Psalmist.
This is how I interpreted the Psalm in relation to "REED".

R (recognize the emotions)
David felt distraught, anguish, fear, hurt, and gratitude.
E ( express emotions to God)
David tells God he is distraught, and he expresses hurt about being betrayed by a friend. David tells God how scared he is. Finally, David expresses his love and gratitude for God's provision and holiness.
E ( evaluate what the emotions are saying about one's thoughts and beliefs).
At first, David wants vengeance, but ultimately he trusts God truth as his authority.
D ( decide to replace lies with God's truth)
David voices the truth about God; that God hears his voice; God ransoms him; God is enthroned forever; God sustains, and brings down the wicked. David ends the Psalm by saying, " I trust you".

Scripture verse:
"Cast your cares on the Lord and he will sustain you; he will never let the righteous fall. But as for me, I trust in you" ( Psalm 55:22&23b).
