You have to learn that what other people think and say of you is always about them and their perspective, not you. It is not your reponsibility to control what they think of you, the only thing that matters is that you behave in a way that means you are proud of yourself. If you are proud of yourself and other people don't "get you" then that's their problem, not yours.

What is to be afraid of? Seriously, noone has the right to scare you!! If people are making you AFRAID then they arent the kind of people you want to be knowing anyway. Anyone who truly matters to you in life will make you feel at ease.
