The Obsessive Devotion Lyrics

Lyric discussion by Dark Artist 

Cover art for The Obsessive Devotion lyrics by Epica

It's about letting go of someone that you love. Even though this person is abusive and unfaithful, you love them anyway obsessively. Towards the end, that line is "I effaced myself for you." And at the end, he lets go and says 'this is the end, I've had enough'. I'd like to know what the Latin parts mean again.
