I'm inclined to say you're trying to answer a question with the same question.
If you confidently believe that love is an illusion because it's just chemicals moving around, you shouldn't need to wonder about consciousness. If consciousness is not an illusion, it still almost certainly emerges from actions in the physical world. You can plug somebody into an FMRI and see that neurons are lighting up when they see the color blue. I just don't think that's convincing evidence that the experience of blue is an illusion.
