His head is spinning and there are colors everywhere, but Kurt's not sure anyone else can see them. It's like nothing makes sense. Or everything makes too much sense and his brain has muffled the words to protect itself from the horrible reality. Slipped on ... something. Stairs? Yes, stairs. With ice on them. Senseless.
Kurt runs, he's not sure where, but he hopes it's a place where the air isn't so thick and difficult to breathe because it may be his heart that's breaking, but it's his lungs that hurt. The only thing that helps are strong arms holding him tighter, holding his ribs and his lungs and his heart in so they don't explode. Soft words whisper, "I'm here. It'll be okay."
Kurt finally starts to cry.
