The spoon theory was devised by Christine Miserandino, as a way of helping her family and friends understand how she lives with chronic illness. She writes about it in her essay ‘The Spoon Theory’ on her website ‘butyoudontlooksick.com’. I would recommend a look as it’s a much better explanation than mine!
Basically, each activity that you might do in a day uses up ‘spoons’. Even little things like boiling a kettle or walking up stairs. You replenish these ‘spoons’ through rest. A ‘spoonie’, or someone with a chronic illness, has to conserve these spoons else they will run out, but someone without a chronic illness pretty much has an unlimited amount of spoons to get them through the day.
If a ‘spoonie’ runs out of spoons they could borrow some from the next day, but this will leave them with less ‘spoons’ to use in the future.
To illustrate, yesterday I was so pleased that I managed to sit up all day without having to nap, and so in the evening I decided to have a shower. However, that meant borrowing a couple of ‘spoons’ from today (climbing the stairs and having the shower took more ‘spoons’ than I had left) so I’m paying the price now. It feels like a backward step as I had been feeling much better yesterday, but it’s a little reminder that it’s going to take baby steps (which is a bit longer than I’d like it to take!).
