Friend or Enemy?

Ana my friend,
I love you so.
My strength won't end,
My dedication I show.

Ana my enemy,
Leave me alone.
My weakness you see,
My fear I've shown.

Ana I love you,
But hate you too.
Please leave; no stay,
I don't know what to do.

Starvation's diet,
This is forever.
Hunger's not quiet,
But I'll eat never.
