You've got to be well to be ill

On Saturday I had a cough. Today I've got a cold and a cough. They won't do the operation if I'm not well. Great Ormond Street have told Mum to ring them if I get worse. "Are you worse?" she says. "Or better?" "Or about the same?" I don't have any idea. She's annoyed because I won't take any cough medicine. It was bad enough being nervous about Friday. It's worse not knowing if I should be being nervous or not.
