Wow, that's a most powerful, beautiful poem and it describes precisely how it feels to be lost in between languages.

I've had the same experience when I spent a couple of weeks only speaking English. It's scary, but you'll find that, once you're back to the UK, after an initial confusing two weeks or so, you'll think, dream and speak 'normal' English again. ;-)

So for now, be happy and proud you're so immersed in another language. Means you're doing well.
