'Desperate' in the Bible

“Do you intend to reprove my words [with a convincing argument],When the words of one in despair belong to the wind [and go ignored]?

In the day that you plant it you carefully fence it in,And in the morning you bring your seed to blossom;Yet [promising as it is] the harvest will be a heap [of ruins that passes away]In the day of sickness and incurable pain.
