Just FYI - in many interviews, you can just say "Sorry, I'm having a panic attack. Could we do this tomorrow?". One of my friends had a panic attack during her Google interview, left came back the next day, and got the job.
So, YMMV, but people are often able to be accommodating for things like this :)
