WHERE 'ME'

I am restless because of what I have felt since I was a child, but now I can't find the right definition of happiness because I feel like there is a missing part of me that I have felt before and it has messed me up a lot. I have many insecurities in my life and capabilities and physical appearance. And until now, when I'm in senior high, I want to find my true self, I want to see and know the reason I lived in the world, what I'm worth, what things I should have done.
