You, I, and They

You don't know it. But sometimes I weep.
You don't know it. But sometimes I cant sleep.
I see you everywhere I go. Inside I'm screaming.
I see you everywhere I go. Even when I'm dreaming.
They don't understand. Why I do what I do.
They Don't understand. How I feel about you.
The world stays the same. Nothing changes.
The world's a book. I'm just turning pages.
I try to say goodbye. Because I forgot how to say hello.
I try to say hello. Because I can't bare to let go.
