OK so... when I was in elementary school I was shy and now I'm in 8th grade and I am STILL shy. I really hate being shy and not showing my true self. At home, I'm very hyper and outgoing but in public, not so much.. :/ I really need some tips or any help how to overcome my shyness :/

No secret, just start doing some things more and more. Only you can make the choice to act or behave the way you wish
