How do you do the "waiting game"?

Yesterday when I heard the news, after my biopsy was taken, that on a scale of 1-5 they gave me a 4 for a probability that I had cancer I was really pragmatic and wanted to discuss all the possible options with the breast cancer nurse.  Today I just feel physically sick and on the brink of having a melt down.  

What hints do you have to distract yourself.  I have a 2-3 week wait for confirmation of the results.

Any advice appreciated.

Thank you.
