"It's hard," Karla agreed, looking down at her hands. "It puts such a burden on you. You have to be the one to fix things for everyone, and sometimes you just want to stop and scream 'Why me? Why not you?' But you can't and people go on being scared and doing what they've always done and you've got to step up and take all the risks and all the dangers."

Okay, that was maybe more to do with Karla's situation, not Katniss's.

"But sometimes it's just so hard, because you're scared, too, but there's no one who's willing to step up for you."
