Many times we get bit confused to know our true nature and it happens because we try to act as people like us to be.
As we get habitual with this quality we tend to get more unhappier in our lives. And it gets hard to explain our opinions for our own self.
Things will get difficult for you, when you express yourself (good or bad) but doing that you will get to know yourself better and can give a better direction for your life. After all there is only one person who can help you from all your misery and that is "yourself".
And if it is only you, why others opinions really matters ?
