First off, I'm not a girl. Second, I think I shall.
I am neither here nor there.
(It's not in two places at once)
You will struggle to conquer me when i'm
at my lowest.
(You try to get it at it's lowest)
For i will trap you for eternity.
(It can trap you and the word 'eternity' has a second meaning meaning a long time so you can try hard for a long time!
See!!!
