Here's one of mine. Just so you know making it up as I go along.

Trapped

I'm gone in this endless world,
trapped in a box, a lonley girl.
Crying my eyes out for all you've
done to me. My soul is crying and
no one can see. Stuck forever, never
to be found, I scream so loud, but to you
I don't make a sound. You can't even see me
to you I'm like a bug. I have many problems,
but when I tell you them, you just shrug.
