Lyric discussion by Outrune 

Cover art for Useless lyrics by Depeche Mode

To me, the "you" and "me" is actually the same person...the same person talking to themself. The person is trapped in a rut of shame and self-loathing, beating themself up and feeling useless. This kinda fits with Freestate later on the album, which is about letting go and recovering from it.
