How to be a more outgoing & approachable person

16F & I've always been an introvert n i regretted not making a lot of friends in sec sch.. so i rlly want to make more friends in jc. I've always been afraid of approaching strangers coz i'm scared of ppl perceiving or judging me as a wannabe friendly kid (which happened to me in pri sch, hence my quiet demeanour).

Idk how to start a long-lasting convo coz usually it'll end w an awkward silence & me daydreaming or thinking what else to say.

Ori is in less than 24 hrs & i'm worried that i might have no friends from my ogl or even my class (since my class is usually dominated by boys). So can any extroverts advise me how to get out of my comfort zone & be more approachable?

Fyi i usually dont rlly get along w zesty or overly extroverted ppl, i usually mingle w ppl who have a similar personality as mine. But i hope to get to know ppl of different personalities as well.
