The deepest cry of the longing heart that has tasted and seen that the Lord is good comes in Psalm 42 & 43. Three times over the course of the two psalms, the cry goes out, “why are you cast down, o my soul, and why are you in turmoil within me? Hope in God; for I shall again praise Him, my salvation and my God.”
Once we have tasted living water, nothing else will satisfy.
“As a deer pants for flowing streams, so pants my soul for You, O God.
My soul thirsts for God, for the living God.”
