Impossible Lyrics

From what i get from this song, I think it means plainly about two people who are in relationship, or maybe not even a relationship. mainly to say, they are just fustrated with each other "you're wearing me out, just wearing me out. but i'm wearing you out." and with all this fustration, they are unable to solve their problems, because both are "impossible" to deal with.
