Beachlover, did you know that many performers struggle with social anxiety? Barbara Streisand suffered from horrible stage fright, but one would never know it by watching her perform. Also Micheal Jackson had social anxiety, but look how great he was when he performed. There is a difference between a performing artist and one who is naturally social. You should take some time and check out some biographies of some famous people. A lot of performing artists "fake" being outgoing socially.

Besides, you are only just 19, plenty of time to develop a better sense of being more socially outgoing. Social anxiety, is "fear of", that can be overcome.
