I don't know how

I'm alone in my head,
No one can change that,
No matter how many friends or even family,
I'm still alone.
Looking in the mirror,
It's not who I want to see,
I've tried and still am,
But I'm disappointing,
I want to scream,
I want to break the mirror!
I want to run from myself,
I want to be blind,
That way I could never see my self.
I want to disappear,
To fade away.
No matter how many people,
Or how many times I'm called beautiful or pretty,
I don't see it,
I don't believe it,
I can't,
I don't know how.
