I thought this was an excellent post by Beth Moore about being gut level honest with God.

One Slender Streak of Clarity

During our separation I remember times when I walked and talked to God at the top of my lungs. Over time things did really get resolved deep inside of me. Somehow Christ did do a deep work in me.

If you ever want examples of people who got gut level honest with God just browse some of the Psalms, Lamentations, or the story of Job.
