I write this with a quivering lower lip and a slightly less shaky right leg than I had 48 hours ago. Now voted out of Strictly Come Dancing, my leg has stopped shaking because I don't have to dance again. My lip has started quivering because I don't have to dance again... It will be a little while before I feel completely normal again. Normal is ligaments not swollen and heart not racing every time I see my diary marked for Saturday. Normal is where most of us ought to be most of the time. But returning to the world is hard. Because Strictly is another planet.
