'Heart Is Troubled' in the Bible

My heart is troubled, and doesn't rest. Days of affliction have come on me.

See, Yahweh; for I am in distress; my heart is troubled; My heart is turned within me; for I have grievously rebelled: Abroad the sword bereaves, at home there is as death.

My eyes do fail with tears, my heart is troubled; My liver is poured on the earth, because of the destruction of the daughter of my people, Because the young children and the infants swoon in the streets of the city.
