Who is the Object of My Anger?

I am struggling with anger. I am trying to understand what is happening in my heart. I am in a situation where I feel anger toward a certain individual. The question I am trying to answer is this: Is any of this anger directed toward God? In all honesty, I don't believe so, but I also know the deceitfulness of my own heart. Jeremiah 17:9 says, "The heart is deceitful above all things, and desperately sick; who can understand it?" Because of this truth, I truly want to see if there is any anger toward God in this situation. If there is anger toward him, then there is a lack of trust in him. If I am lacking trust in God, then who and what am I trusting in?

I suppose the reason I don't think this is God-directed is because I have hope in this situation. I believe it was necessary in order for God's will to be accomplished. I believe the promise of Romans 5:3-5, "More than that we rejoice in our sufferings, knowing that the suffering produces endurance, and endurance produces character, and character produces hope, and hope does not put us to shame, because God's love has been poured into our hearts through the Holy Spirit who has been given us."

So, I am struggling with anger. Is the object of all anger ultimately God, or am I being too introspective?
