'Bitterness of My Soul' in the Bible

Also I -- I withhold not my mouth -- I speak in the distress of my spirit, I talk in the bitterness of my soul.

My soul hath been weary of my life, I leave off my talking to myself, I speak in the bitterness of my soul.

-- What do I say? seeing He said to me, And He Himself hath wrought, I go softly all my years for the bitterness of my soul.
