I think its ok to be introverted. I have learned that if I'm feeling quiet in a social setting, I just show interest in others. Ask them questions and let them do the talking. People love to talk about themselves, I like to listen. Win win. And I try to show more interest in them which takes the focus off me. Think less about me and how I'm being perceived and more about them. Accepting me as I am and not worrying about what others think of me helps.
