“When you catch yourself catastrophising in this way, try to take a step back and look at the bigger picture. With the right toolkit, we can come to realise things aren’t as bad as they seem – and so the fear becomes less intense. The scientific name for this process is ‘cognitive reappraisal’: changing the interpretation of a situation so that we feel better emotionally. The main goal of cognitive reappraisal is to shift our perspective on an event, thought or feeling, allowing us to experience a more positive emotional response. A simple way to put cognitive reappraisal into practice is to remind yourself that the thing you’re feeling so bad about probably won’t matter that much in the future. You can do this by asking yourself the following three questions, which add up to what I call the 10/10/10 rule.”
