You don't have to change who you are, but maybe take this as an opportunity to be more social. If they're in the kitchen cooking and eating together, go down and talk to them/ eat in the kitchen etc
If you over think it and think they don't like you, it will become a self-fulfilling prophesy and you'll end up retreating in your room all the time. Go in with an open mind and a willingness to be friendly and social and a willingness for you to be open to them. You're focusing on the worst possible scenario, what if they're amazing really nice people. People can still be the clubbing type but friendly
