Why does she do this? Why does she push so hard on him every time he tries to help? It's reflex, a habit she knows she has and can't break. She's been trying so hard to break it, but her lack of success is plainly obvious.

"A distraction would be nice." She's trying to focus on what he's saying, not what she's feeling. Work through things, not push them aside. "I was honestly planning on hiding away for the day, not seeing anyone if I could help it. But a distraction of some kind would be welcome." There's no need to mention that she was debating setting up the target dummies she purchased and railing on them with her blades until she physically couldn't anymore. No, doing something with him, or any of her friends, would be better than not taking care of herself.
