Well if you can feel the pain then it must exist. Get a second opinion; if you can afford it, that is.

And don't worry about the book. Just keep plugging away, don't give up!

As for me, I keep getting people on the phone that I blatantly can't help and have to transfer. Some whiny b!tch refused to believe that I really couldn't help, and a supervisor told her exactly the same thing I did, which really annoyed me.

@ Quin and smittenkitten: Good luck in your exams. I had to do six in 3 days one time, but they were mostly one and a half hour GCSE exams.
