Are Teens Today feeling Alienation & Isolation?

A question I have is Are teens today feeling alienated or isolation? I noticed during lunch there are many people around and they all fit into their little groups. Most teens don't fit into a certian group. Or maybe when your in " grounded " and have to stay home in your room you feel alienated. I know the feeling of isolation because when a friend is mad at you and another friend takes sides your left alone when your actually not alone but since they are leaving you out your feeling a type of way which is called isolation. I truely feel teens are feeling isolation but I'm not really sure about alienation.
