Charles Ellicott Commentary Psalms 69:3

"I am weary with my crying; my throat is dried: Mine eyes fail while I wait for my God." — Psalms 69:3 (ASV)

Crying. —Better, calling, i.e., on God in prayer. For a similar picture of utter dejection, compare to Psalms 22:15. The following English lines have caught the feeling of these verses:

“How have I knelt with arms of my aspiring
Lifted all night in irresponsive air,
Dazed and amazed with overmuch desiring,
Blank with the utter agony of prayer.”

St. Paul, by F. Myers.
