Feeling A Little Calgary Sick

So work hired a new Director of Education. They had been looking to fill this position since February and everyone is ecstatic about having her on staff - well everyone but me. I had been taking over most of those responsibilities (at a fraction of the salary) but because I'm too young, I don't have 2 years of experience in the classroom (aside from my practicums) or a credential in this state (didn't pay the $300) I couldn't be formally hired for this position.. So I'm frantically worried my hours will be cut, my jobs will be handed over to her, and I'll be pushed to working evenings and weekends and all that other lovely stuff.. I feel like I've been used. In walks the new DE that everyone is worshiping, and here I have to hand over my desk, my computer, my responsibilities. I don't get it but whatever.
