She says a slough of things that are beyond Sakura's comprehension, but the important parts hit her hard. Being told such things by... her parents? That's way worse than the harsh things Sakura has been telling herself. At least she's had people who were understanding and didn't fault her for it, even though she accepted full responsibility.

And not having a heart? She's feeling all of this pain right now, so how could any of that be true?

Furthermore, though, her attempts to cheer her up prove to be useless. It looks like she can't just parrot someone else's words that were meaningful to her and expect it to have the same results without the proper context... This girl must have them, too. Words that she desperately needs to hear. Sakura wonders what they might be. She doesn't know, but she can't just leave her like this.

"That's awful, saying those things to you..." she says sympathetically. "I understand how much those feelings can hurt, how hopeless you can feel. But, you know— It isn't over yet. It isn't over until you decide it is! Don't let someone else tell you what your value is! Show them what it is yourself!"
