Courtney is a worrier - she's worried about everything, from her mum and dad's constant fights, to her Gran being ill, to the fact that her best friend Lois suddenly seems to be more interested in growing up and hanging out with mean girl Bex than with her.

If the worry magic could fix things, could it even make GRAN better? COULD IT?And what if I worried about Gran actually on purpose? Could I panic myself, bring on the magic, and CURE her?Whoa! This was so freaky.But it was worth a try . . . and why not RIGHT NOW?I ducked right under the water, and screwed up my eyes tight. I didn't really want to, but I made myself think about all the horrible, scary stuff to do with Gran . . .Coming home that day to find her gone . . . Dad telling us about the ambulance . . . his frightened face . . .I imagined Gran lying there with her tubes stuck in her . . . not getting better . . .Brrrrrrrr!I shivered under the water, and popped my head out with a gasp, my heart beating loudly in my ears. Ugh, it was working. I was really upsetting myself. But I couldn't have a worry-dream in the bath - I might drown.I clambered out, wrapped myself up in a huge towel, sat on the bathroom floor, and carried on worrying and worrying.I worried until tears were dripping off my cheeks.But still no dizzy feeling came.Still no magic . . .I sighed, and rubbed my face hard with my towel.It was hopeless. I couldn't MAKE myself conk out or have a dream. It was like trying to sneeze - just impossible.The magic didn't seem to work long-distance. But I was sure that if I saw poor, ill Gran - up close, with my own eyes - I'd get so, so, SO worried that the magic would come straight away.I pulled my dressing gown off the back of the door, and dragged it on.Dad had promised to take me to the hospital on Saturday, if Gran was well enough.That was the day after tomorrow.Yes . . .Please come then, worry magic!
