It's important to be different, but you don't want to look like your from Mars. If you do, people tend to pick on or look down on you. Seek out a club with interests like yours. If you like to write, join the magazine or newspaper club. If you like acting, show your talent in the school play.
Sport teams are great too.
Invite friends over to your house or to a movie, as this may help tie your friendship together. Ask your parents to invite a few classmates and their parents over for a pool-party or a barbarcue. Some groups revolve around on person. The person in the center can get very stressed because the other members watch their every movement. Often, when the central person makes a mistake, the surrounding group of admirers back off, seeing they aren't perfect.
