Control your contribution. If you’re quiet and introverted then value you who you are. Don’t expect yourself to be a party animal. Show respect for yourself by taking time out if you need to, and only talk to people that you want to be around.
See it as a chance to practices a few social skills. Take the pressure off yourself by practising your social skills. For example, ask a few open questions, and keep the focus on the speaker. Try and come across as friendly through your use of body language – like making good eye contact and smiling while you talk.
