Recovering corrupted memo in Notes

Battery issues have been killing my Galaxy J3 Emerge at random times, and yesterday I was writing in a Memo that I have been compiling text and audio for the past several months, and my phone died. I don't specifically remember if I was in the act of saving the note or just typing in it, but the phone died and when I turned it back on, the note wouldn't open because it said the file may be corrupted. I know a corrupted file is often a lost cause, but something as simple as a memo just makes me think there could be a way to recover. Even if I search a particular word that I know is in the note, it will pull that note up. So the contents are clearly still there, just inaccessible. Any hope?
