riptide 

(ˈrɪpˌtaɪd  )
 
noun
a current opposing other currents, producing violently disturbed water; esp., the strong, narrow flow of sea water that rushes after incoming waves pileup on the shore

Loss comes over the body like a riptide. There is some relief from swimming with it. Wind pulls patterns on the surface tension. The lens of the eye shuttles between blur and focus. Sound bubbles in the ears like liquid thunder. Three words repeat: trust the water.
