Uninvited guest

There's always someone there
Watching my every move
He knows what I'm thinking
And sees everything I do

I tell everyone I'm good
Never felt better
But he knows the truth
The noose is getting tighter

I run but he follows
Always in my sight
Try to walk the straight and narrow
But he pulls me to the side

He pulls me under
My uninvited guest
I know I'll be forever
Forbidden to take rest

What else can I do
I'm just playing host
Eternally possessed
And haunted by my ghost
