According to a recent study from Edinburgh Napier University, Psychologists believe that those who are most addicted to the website can develop 'Facebook-related anxiety' as they agonise over online friends.
Many said turning down friend requests left them feeling guilty, while more than one in ten found just being on the site a 'nervous' experience.
Others could not handle the pressure to be 'entertaining', while others became 'envious' of users who had more friends or seemed to be having more fun than them.
Dr Kathy Charles, who led the study, said: 'We found it was actually those with the most contacts, those who had invested the most time in the site, who were the ones most likely to be stressed.'
Would perhaps this excess stress explain the eating disorders associated with the popular social media site?
