Cover art for Blessed With a Curse lyrics by Bring Me the Horizon

I think it's about not feeling worthy of someones love. Im guessing probably Amanda. He loves her but he also has "vices", probably drugs and alcohol, and he feels like they are the two greatest loves in his life. I guess someone struggling with addiction would feel pretty conflicted over the people they love and their vices. I think the whole "Everything I touch turns to stone" part just emphasises that he feels like he's not worthy of love, especially if he has been lying or misleading to that person about his vices.
