First, the obvious: the title gives rise to a theme of the victim embracing the captor as in the Stockholm syndrom. You carry this theme through beautifully as you merge with the darkness and fall in love with agony. The cost is paid by swallowing your emotions, denying the honest expression of your innermost feelings. Inevitably the process consumes you, it wreaks vengeance on your peace sinking you down. In the end there is nothing of you left.
