How can I stop being an introvert?

never force yourself to be somebody you arent. especially if your trying to stand out more. the people your hanging around with arent the best type of people to hang about with if they think your wierd. if i were you, id look for some of the much quiter people in class and begin talking to them. i bet that they will have more to talk about with you, including both of your confidence issues. youll most probably end up becoming good mates with them...
