I've been invited to a party. I want to go, but I'm afraid. I'm a introvert and can't talk to people. What should I do?

Ik parties are cool😭NGL I'm not a party person. Apparently I should do things that scare me in order to cure myself of my introversion. I'm confuse. How can I survive only knowing 2-3 people and being socially awkward/anxious?
