So who says you're unwell? A doctor? Your insurance company? You? Your boss?
What makes a disease is a slippery slope of definition, and not for the faint hearted (which could itself be a disease). It makes a vast difference to how - or whether - you're treated. Do you get a day off work? Will you insurance company cover you?
Just as important perhaps, it affects your own well-being, and your perception of whether it's okay to feel crap. Or whether you're a shirker, a malingerer and a sponge bunging on a sickie.
This is no trivial question if you've been told to get over it, come back tomorrow.
