Some of the things I do are clubbed under the term obsession. I don't know if this is true. But now I have a word for it - idée fixe - pronounced ee-day-FEEKS. It seems like a more fashionable word whether it is an obsessive behaviour or not. Just like suffering from migraine or having a bout of food poisoning rather than a dumb term like headache or an upset tummy. They mean one and the same.
Coming back to the idée fixe that I am supposed to be indulging in - like mundane activities - cleaning the house, washing the clothes etc etc. All I know is that these need to be done - the sooner the better before it becomes more of a problem resulting in severe migraine :-).
