Oh sweetie....that's terrible! Well, you are most likely better off and I'm sure something better will come your way. I don't get how that termination doesn't allow for unemployment, adn is there some way of tracking your overtime hours. . If you have records of that, the very least you can do is complain to the BBB. Let other out there know how they work and what they do to their employees. If you have those OT records and non payment, surely you can do something about that?
I have a friend in Germany going through much the same thing. things will look up for you I know it. In the meantime, have a good sleep in today, and terrific cup of coffee and gain a new perspective.
