I had a friend who had chronic anxiety and was a hypochondriac... great bro, now rocks out in a band is now making it name known in chicago, but he was convinced that his intuition was telling him he had HIV, well I tried to talk him out of it, the next thing I know, I think I might have HIV too... so we here we are, fully deluded so insistent that we both have a high probability of having HIV, that we got tested 2 hours later... the whole mindset was stupefyingly surreal... this was during my undergrad years, but longest week of my life... one should be careful of the information they let in cause the descriptions you entrench yourself in conduct your perception.
