My Name Is Ana

Hey, my name is Ana,
I live inside her,
I manifest throughout her,
I take over,
I spit horrible thoughts into her head,
I make her believe this world is a horrible place, 
I lie,
I make her see the world will end if she fights me,
I lie,
She still believes me,
I'm winning,
I allow her to think she's escaping,
Then I simply reappear,
She dies inside a little every time,
Theres no easy escape,
She knows this now,
So why does she still try?
