There is more and more talk about a modern disease called depression, and this disease most often occurs in young people. It is not at all harmless mental state and feeling of inferiority, which, if left untreated, can leave serious psychological and physical consequences. Social networks and the media, in addition to parents and the environment, have the greatest impact on children and teenagers.
