text: I guess you need to be careful when learning about the introverts. And I find this question is a bit offensive, because you measure us from an extrovert point of view.\n\nYou must know, that most of the psychological criteria just list the condition of certain mental illnesses or disorders. There are no clear words or lines in the DMS-IV-TR, says that we introverts are prone to suffer from Neurosis.\n\nI believe there are many different reasons behind for people to suffer depression, anxiety, low sense of self-worth, and so on. Having such conditions, doesn't really mean that a person suffering from Neurosis.\n\nWhy we introverts have similar conditions? Is just simply from excessive loneliness that we experiencing, which cause by incapable of making and keeping friends.
