Psalm 6
A raw psalm of sickness and tears: bones in agony, a bed flooded with weeping all night, and "How long, O LORD, how long?" It doesn't get tidied up quickly. The turn in verse 8 comes not because the pain is gone but because "the LORD has heard my weeping." Being heard is the first mercy.
"I am weary from groaning; all night I flood my bed with weeping and drench my couch with tears." (Psalm 6:6)
