Hate to be a promoter, but if you go to Classmates.com or Facebook you may be able to find your old buddies and keep in touch long-distance, if you have a computer. For making new friends, you just have to get out there and meet people. You may not find real friends the first few times you start to mingle, but eventually you will find people you are comfortable hanging out with. That means, attending local events, school events, joining school teams you may have an interest in. In the meantime, don’t get too lonely while waiting for your social scene to improve. Maybe do some solitary activities for a while like reading good books, learning a new sport, watching some movies and doing things that would help you grow as a person.
