Chasidut su Salmi 69:4

Once, I had been complaining to him about my problems and I said to him bitterly, "I am worn out from my crying, my throat is hoarse, my eyes are spent from hoping for my G-d" (Ps. 69:4). And he raised his hand and said gently, "If so, what is there to do?" (In other words, it is forbidden to question the ways of G-d, and G-d is surely righteous). Afterwards he answered and said to me, "If Kind David a"h said "I am worn out from my crying, my throat is hoarse", surely he meant it literally: he had already cried out so much that he was physically exhausted and his throat was literally hoarse. But you, thank G-d, still have your strength.
