In Jeremiah 31 :15, Rachel is representing a Nation or System which is gone. A Nation which is facing captivity. In a figurative sense this can mean as well a failed project, lost work, a failed marriage etc.
BUT, you need to CALM down, as if you are mourning you will not hear gods instructions.
Do not refuse to be comforted.
See Jeremiah 31:16-17 and rejoice Jeremiah 31:13
