Smart phones are also the cause of depression among teenagers. Child psychotherapist Julie Lynn Evans says that she dealt with one or two attempted suicides a year in the 1990s, but now faces up to four a month. Lynn Evans blames smart phones for this increase, saying that it allows teenagers to carry a world of cyber bullying with them wherever they go. "There are diffcult chat rooms, self harming websites, anorexia websites, pornography, and a whole invisible world of dark places. In real life, we travel with our children. When they are connected via their smart phone to the web, they usually travel alone," she says.
