You managed to get outside? [He sounds surprised, as stupid as it seems. He realizes it sounds stupid, though, so he quickly explains:]

If I get more than a couple feet away from this stupid station I feel like I'm going to die.

I threw up... something that didn't look like anything I ate. [and it made him feel a little queasy remembering] If someone hadn't helped me back, I don't think I could have made it. I can't imagine how bad it would feel if I tried to get out to the parking lot.
