You're right, that it all hurts you. But you could just as easily say some of those targeted me. Or the recipients. Imagine how awful Syaoran felt when he realized he'd just forgotten you.
Jinx's duplicity... Syaoran's guilt and existence, Watanuki's life, my position, your vulnerability... she wants all of those.
She couldn't get you, so she hit you as hard as she could another way.
