There's a term that gets thrown around a lot – keyboard warrior. It's used to refer to someone who makes aggressive or abusive posts online, often anonymously. I like the name. In my mind, when I read something especially horrific on my feed, I imagine it's written by a lone person unacquainted with personal hygiene practices, dressed in a poorly fitted super hero costume – one that is baggy in all the wrong places.

Sometimes when I'm in the first round or second round, and I'm not playing well, I say, okay, just accept it. Don't get frustrated. Just accept and focus.

Yes. Today has been really stressful. We had a workout this morning. It went okay. And then just that five and a half hour wait or something. I was just shaking, could barely nap. I've just never felt like this going into a competition before. And I tried to go out here and have fun. And warm up in the back went a little bit better. But then once I came out here, I was like, "No, mental is not there. So I just need to let the girls do it and focus on myself."

Don’t panic. Midway through writing a novel, I have regularly experienced moments of bowel-curdling terror, as I contemplate the drivel on the screen before me and see beyond it, in quick succession, the derisive reviews, the friends’ embarrassment, the failing career, the dwindling income, the repossessed house, the divorce . . . Working doggedly on through crises like these, however, has always got me there in the end. Leaving the desk for a while can help. Talking the problem through can help me recall what I was trying to achieve before I got stuck. Going for a long walk almost always gets me thinking about my manuscript in a slightly new way.

I don't think I could go for another three years. I'm leaving it at the right time, I love it, I've absolutely had a wonderful competition and I've loved every minute of it.

I love swimming and I'll still be found in the pool, but now I'll be able to do without the 04:30 alarm!
