I agree with praying Psalm 37, I have prayed it many times in my life since I was very young and God have answered my prayers. Today those who tried to hurt me have moved far away, and no more contact with me. The rest are no longer in this earth like the Psalm says, they have whiter away like the grass. We who love God are protected by the blood of Jesus Christ, and God hears us and answers us. He even let us see the destruction of the wicked, as log as we restrain from anger and leave it all in God's hands for he is the only one that can fight our battles better than we can ourselves.
