Prayer for When I'm Feeling Angry

Heavenly Father,

my heart is so full of hatred and anger.  I dont know where it comes from, but I know that I am constantly angry.  I find myself thinking thoughts that would be hurtful and shameful if said out loud.  I dont want to be this person who struggles to have a soft heart.  Please transform my heart from being hardened and full of anger to a softened heart full of love.  I know the most important commandment is to love and I want to follow that commandment to shine your love on others.  

For he will deliver the needy who cry out, the afflicted who have no one to help.
— Psalm 72:12
God is our refuge and strength, an ever-present help in trouble.
— Psalm 46:1
