Loneliness. According to San Diego State University psychology professor Jean Twenge, 67-78% of teenagers in highschool have felt that feeling of “utter loneliness” even when around friends. One student described it as “the experience of sitting in your room and you don’t know who to call when you're sobbing, feeling at your lowest, and you have to sit there in the silence. That's what loneliness feels like”. Twenge's Research has shown that people with weaker social relationships have a 50% increased likelihood of depression compared with those with stronger social connections. The reason for this is not known for sure, but it is thought that it has to do with human brains programmed with a craving for connection and interactions with others.
