It's a little weird for you to ask people over the Internet if they think you're pretty. It makes you look like an attention-seeker. No offense. Event though that sounds extremely offensive. Sorry. But the only way to determine if you're as gorgeous as your friends say you are is to embrace your best features, and look in the mirror. Accept what you see, then make sure you're personality is more gorgeous than your face and your body.
It doesn't matter what people think of you, it's what you think of yourself that masters :) and even if you don't think your pretty, then if everyone else says u r than u need to be proud and believe them! :)
