Why should we fear?

Here I am, Fighting, My life is on the line, The doctors say, Don't give up, The truth is, The path is rough, All the tears, all the hurt, The prayer has to work, I get on my knees, and look up, And ask for God's help, I am tired of being sick, Of losing my hair, I am tired of being scared, I want to live, for my son, the battle has just begun, But I am going to fight, and I am going to win, and keep praying, and I won't lose sleep, I will not fear, I will just thank God I am here.
