I mean, completely irrational? Years ago, I was involved in a bit of an incident.. which did lead to a lot of medical complications in the long/short term, and the last year has been not so hot that way.. At the same time, amongst all of it, no matter how many tests we run or suggestions doctors have, you start thinking completely irrational fears (like you demand to be tested for the same thing you were just tested for a few months ago?) I know, strange. In the end, it always comes back to the same reasoning, but still.. you keep pushing to redo tests, even though they (medically) don't make sense but you don't like doctors who answer "hmm.. I don't know.."
