There's a possibility that you may suffer from mood failure, which is a form of chronic depression, which can cause a range of physical and emotional symptoms, such as poor speech, anxiety, phobia, or loss of interest in sex.
Doctor, I've been having strange symptoms recently: I've been spoken down, I've been antisocial, I've always been anxious, I've always had anxiety, I've got fear and phobias, and I've completely lost my sexual appetite.
