One form of “checking” behaviour is comparison. This is when you constantly compare your physical attributes to those of other people. It can be challenging to stop negatively comparing yourself to others: for many people, it’s such a habit it is automatic and happens hundreds of times a day. Try to notice when you compare yourself to others and make a note of when you compare, who you compare yourself to, and what you say to yourself when it happens. Is it fair? Is it realistic? What effect does it have on how you feel about yourself? What can you say that may be more helpful?
