Have you ever had a minor setback at work and immediately thought, "I’m going to get fired, lose my flat and ruin my life"? Or perhaps a friend didn't reply to your text for a few hours and you instantly concluded that "They hate me, I've done something wrong"?

Have you ever had a thought that made your stomach drop, only to realise later that you were panicking over nothing? Perhaps you sent an email to your boss, didn't receive a reply for an hour, and immediately thought, "They are going to fire me"
