How can I show people I'm not shy or afraid?

Just be youself.Try not to care about others.If you really want to prove to them,then go talk to them. Good Luck! ^^

You don’t need to prove yourself to anyone.

I personally consider myself an introvert, but people like to assume I’m shy - when they first meet me anyway. I don’t know how they get that.

wow you are really just like me. LOL. I am quiet but as long as long as I am with my buddies you know the quieitness will naturally go away when we have fun together. SO hang around people who are different from you but accept you for who you are. You will see that you will start to act out more than usual because you are in a group.Then when you do that often it will turn into a habit then into a character. Soon people will notice that you are not shy. But you know xigxag is right don’t do this to prove to anyone. Do it because you want too.

I’m going to get some flack for this.Pick the weakest guy in your class, and snap and beat the crap out of him. Or you might just try keeping yourself around people, either in a lounge, or try running for positions in groups, so as you work with people, you can establish friendships and relationships with people. Both tactics have worked for me, the latter being more fulfilling, but less fun. :-)
