I get what you mean completely. There are a few people I have in my friends on Facebook who go to my school and could be considered "popular." They never talk to me, but they're always posting about their friends and what they're doing today, and about their relationships. It makes me really jealous, because I don't have much of a life like they do. Sometimes I get depressed because of it, and I just have to get off of Facebook. But I agree that just because someone is friends on Facebook doesn't mean they have more of a life than you. They could have friends on their Facebook's they never even talk to in real life. You just never know. So I wouldn't let it get you down too much.
