I haven't tried CBT so I don't know much about it. It's to do with changing thought patterns from negative to positive, right? So when you don't receive a reply to an email you sent to a friend, instead of thinking it's because they don't like you, CBT encourages to think more positively. They might be having internet problems so they can't reply, something like that. Is that the basic idea? My question is... Isn't this just fooling yourself in a way?
