I need to pop the shy bubble?

ok. so im like this really shy girl. im not as sociable as everyone else. how do i build my confidence and become popular. i get picked on alot because im shy. i can't really shout. what must i say for say e.g someone mocks my culture? but without swearing. im only confident around my friends.I need to pop the shy bubble?
i have a friend like that, she is always worring about what other ppl think, and i thinks its her worst quality, its good that u would like a change, i think all u need to do is if u wanna do sumthing and think ppl will think its weird, just think,"what can they do to me if i do this?" ppl wont make fun of u for being urself, inless ur reallly weird, but u dont seem it. haha, just dont let other ppl stop u from doing wat u want.I need to pop the shy bubble?
it's not bad to be quiet. i'm very loud and outgoing and my best friend is extremely quiet and reserved. if your friends like you for who you are, isn't that good enough? if you do want to be popular, start making conversation with others who you don't usually talk to. Start with a few jokes about the boring project you have to do, say hi to them in the hallway, ask they homework questions. hopefully they start talking back with you and a friendship forms
