In cases where a feeling of jealousy covers the entire consciousness, subjugates behavior, changes perception, then the help of a psychotherapist or psychiatrist will be required. In mild cases, pathological jealousy manifests itself in the form of obsessive thoughts, a person may remain critical of his condition and understand that he cannot cope with it on his own. In severe cases, the obsession turns into delirium (erroneous conclusions that cannot be dissuaded), critical understanding is lost, and here help is possible only in cases when relatives notice this and can organize an examination by a psychiatrist. Only treatment can get rid of such a feeling of jealousy.
