Lost without you

I'm here yet I'm far beyond reach.
I'm moving forward yet I'm standing still.
I listen but the noises don't get through to me.
I learn yet my knowledge is unattainable
Think but my mind is blank.

I'm laughing but why am I crying out.
I'm soaring high yet my feet are stuck on the ground.

My heart is racing but...
... I'm dying slowly and silently.
