stop being so quiet

I dont really think anyone I know goes on this, but here it goes..

I hate being quiet, it really bugs me.
I started highschool this year, and in class im very quiet.
like, i talk to my friends and i do have alot of them to.
its just some ppl talk about how quiet i am, but i cant help it. i mean i dont chose to be quiet, its just so hard to be like some ppl who shout and yell things in class. mostly because alot of ppl who are in my classes,arent all my friends. I only have like maybe one er 2 friends in all my classes except one, and alot of the girls intiminate me, like i dont talk to them reallly..and i dont know why, i’m just soo shy..
god i sometimes hate myself. its me awhile to get use to the ppl im with.
i just wanna know that theres more girls out there like me, so i dont feel so alone. i cant help it im so quiet, its just i was born that way…

i hate being quiet so much sometimes. it’s not that i’m shy, i don’t think, i just don’t have anything to say. like seriously. when i look around, it seems like everyone makes friends so fast, and everyone is laughing and having a good time so easily, i just don’t understand how they do it. it comes so naturally to them, and it seems like if i confronted or asked them about it they’d just say something like “Speak your mind!” but the thing is i just feel like i don’t even have a mind to speak. sometimes i feel like a part of my brain is just MISSING, i feel so blank and boring. it’s such a lonely bad feeling and i really dont feel like most people would even understand, even my boyfriend (to whom opinions and talking comes very easily). is there anyone else out there who feels like this?

I just don’t want to be so quiet. I want to be loud. I want to speak out! It’s hard to do though, I’m scared of saying something wrong.

I don’t like not speaking my mind and regretting it later, and the fact that I have to repeat every sentence three times for people to hear me. It’s not that I don’t want to talk, it’s just that I’m always (if only subconciously) thinking I’m going to say the wrong thing.

It’s not that I’m antisocial or mean or stuck-up. I just don’t know what to say.
