Just Leave

Why can't you just leave,
Its so easy for you to do.
But your stuck on my mind,
I can't get you out.
I tried to drown you,
But you swam.
I tried pushing you out,
But you dug in deeper than ever.
I tried leving you in the dark,
But you made your own light.
I tried replacing you,
But you just moved to the back,
Not gone, always there.

Maybe you did leave,
And my mind is stuck on you.
