Just try to think of something else...otherwise figure out what you are going to do if the results are bad.
Go to an art house cinema and request they roll Cleo de Cinq a Sept.
Play videogames. Think about how my life would end if I came back positive. Be thankful that I always wore protection when I was single, which distinctly cut down my changes for contracting anything serious despite being a slut.
O man, it so sucks. The first time I took an HIV test I had to wait two weeks for the results. I pretty much stopped eating and lost 11 lbs. I wasn't sleeping. Out of nowhere I would suddenly need to puke. After getting the results back, I vowed never to do anything even remotely risky again just to avoid that hell.
OP try watching a funny movie, one you have not seen before. Surround yourself with people as much as you can. Playing video games also helps. Whatever you do don't drink or smoke pot. That makes it MUCH worse.
Use OraQuick for god's sake.
Oh, I thought you meant tests like the LSAT or MCAT.
I sneeze on strangers, don't wash my hands after doodying and spit in people's food when they're not looking - just in case.
