It could be that but it could also be my possible avpd? What do you mean "everyone is doing better than you are"?
Sorry for the late late reply.
In the sense that, if you're comparing yourself to others, then your self-esteem must be low, and therefore you'll always feel as though other people are doing better than you are (better jobs, better social and romantic lives, etc).
First make mental note of your current situation, what you're afraid of, what you can currently do, etc; then start working on each of those fields individually until you become more confident doing them.
