The tide is on the ebb.

Sarah was at a low ebb for several weeks after her mother died.

His popularity was at a low ebb.

She has been with me through the ebb and flow of my fortunes.

But when Ulysses, fain / to weave new crimes, with Tydeus' impious son / dragged the Palladium from her sacred fane, / and, on the citadel the warders slain, / upon the virgin's image dared to lay / red hands of slaughter, and her wreaths profane, / hope ebbed and failed them from that fatal day, / the Danaans' strength grew weak, the goddess turned away. / No dubious signs Tritonia's wrath declared."

All my energy has ebbed away.

Relations between us seem to be on the ebb.

Every tide has its ebb.

Life ebbs and flows.

I walked along the beach when the tide ebbed.
