Escape cruel au pair family

I'm in a catch-22 living in Holland as an au pair. My family is using me incorrectly and works me like maid or servant. I have been in touch with the agency but unfortunately for many cases such as mine if a new family is not found for me, I will be sent home. I'm raising money for when worst comes to worst and I need to fly out or otherwise run away from my au pair family. My only other option is working here until I have enough but with the extreme hours I'm not sure how much longer I can handle it. Please donate toward my cause! Any little bit helps!
