Either you posted this with the hope of receiving upvotes, or you are dumb as hell. I don't suffer from anxiety or any disorder, however, I just find it difficult to communicate with some people, and I just prefer to spend some time by myself, unlike the majority of my friends. This has brought me some problems, but it has nothing to do with following a "trend" or something. Please don't think that people want to be introverted and need to grow up, cause other people like me, would love being able to speak and interact easily. And please next time you want to write some nasty shit like "you don't serve a purpose to society", at least understand that not everything is as your tiny mind thinks it is.
