'Complaint' in the Bible

When I say, My bed shall comfort me, my couch shall ease my complaint;

If I say, I will forget my complaint, I will leave off my heaviness, and comfort myself:

My soul is weary of my life; I will leave my complaint upon myself; I will speak in the bitterness of my soul.

As for me, is my complaint to man? and if it were so, why should not my spirit be troubled?

Even to day is my complaint bitter: my stroke is heavier than my groaning.
