I assume you guys are in high school right? Basically this is what I pretty much did up until sophomore year. I went home and did stuff by myself and whatnot. Come junior year I started getting into other hobbies, sports, and clubs. As a result I met a lot more people with similar interests and I began to develop more "real" friends over the year. Sure we'd go to my house and play video games and other stuff, but doing these activities with friends is what sets it apart from doing stuff by yourself. Highschool pretty much sucked, but hanging out with other kids every other day was the redeeming factor. Once you get into college you'll be with friends pretty much every time you are free.
