It is very natural that we will feel a little shy when we are surrounded by strangers. But we can try to get rid of this feeling .I would like to give you some suggestions.

First you should try to take part in some activities to improve your ability. And in the meanwhile you should try to begin conversations with others. Second ,if you want to be outgoing ,you should have enough self-confidence . Finally you should make friends with outgoing people and learn something from them .As long as you try to do as these ,I think you will be less shy.
