With what a deep devotedness of woe
I wept thy absence - o'er and o'er again
Thinking of thee, still thee, till thought grew pain,
And memory, like a drop that, night and day,
Falls cold and ceaseless, wore my heart away! ~ Thomas Moore

I think this poem means the person though is spitting him or her in pain so he's asking whoever to wore his heart away which mean to make his heart feel better stop it from hurting.

Your interpretation doesn't make any sense at all !

This so much like a homework question.
