It is rather doubtful (as in the parallel passage, Jeremiah 4:19-21) whether the speaker here is the prophet, or "the daughter of my people," who, in Jeremiah 6:26, is called upon to "make most bitter lamentation."
Of course, the prophet cannot dissociate himself from his people; and we rosy therefore, perhaps, consider both references united. Hurt; literally, breach; a term so used for political calamities. A grief; rather, my grief; but "grief" is meant to include both physical and mental sufferings (literally, my sickness).
