Well, it sounds like you have something similar to hypochondria. HypoC (cant be arsed to spell the whole damn thing all the time) is when - for example - you have a headache, and you think youve got a brain tumor. You start coughing, you think youve got Bird Flu. You get a broken leg, you think youve got gangrene etc etc.
HypoC is the closest thing I can think of that youve got. It sounds like ittl be able to be sorted out with a little bit of therapy each week anyway, so hopefully no nasty tablets to swallow each day.
