If your friend says ‘I’ve started going to the gym’ it is considered undisputedly positive; if they tell you ‘I’m getting CBT’, suddenly the atmosphere becomes tense. They seem to feel awkward as they tell you, and you don’t quite know how to react. They might as well have told you they’ve contracted an STD. But Cognitive Behavioural Therapy — ‘a talking therapy that can help you manage your problems by changing the way you think and behave’ — is only good for you. It is evidence of a sensible choice. And yet, sweating, starving and interfacing with an inanimate, rectangular scale every morning, is more attractive to people than sitting in a comfortable chair and talking leisurely with someone you trust.
