Do you spend a lot of time worrying about whatever disease/disorder you may have, or is it more like a curiosity/habit?
When I was a kid, I was always thought that I might have cancer. No idea how that got planted, I didn't know anyone with cancer. I spent 5 or 6 years thinking I had MS, because I would get these numb patches on my skin, along with some other symptoms that I probably imagined. I recently really thought I came back from India with intestinal parasites. None of these things turned out to be true, but I don't think three imagined diseases qualifies me as a hypochondriac. I had reasonable cause to be concerned about the last two.
But getting the tests for those latter two and the negative results made me feel a little silly. Relieved, but silly.
