I think you're confused about the name change. All of your posts prior to the swap were changed from the old name to the new, leaving zero posts for Haleyja. The only way your old username would have any posts is if you've used it again since the name change was done.
I suspect you're having trouble finding the poem because you are misremembering the title and, perhaps, making your search criteria too narrow to find deriviatives. You originally posted it in Open #10 as Her Ever Constant Star.
