Help with Director?...?

I was recently cast as the lead in my high school's show after doing three consecutive professional shows, so I'm kind of used to that kind of theater. My school director, however, isn't. He's rude, mean-spirited, and has to have things his way: he forces the actors to do exactly what he says, down to the position of their pinkies (This sounds like exaggeration. It's not.) and I think he mildly dislikes me and as a result, publicly humiliates me. In addition to not letting any of the actors have any say in how the scenes run, he is constantly putting us all down (me especially) telling me that "He should have chosen someone with more acting experience." I can handle criticism (it's kind of a part of professional theater) but he's just unkind. I find myself dreading rehearsal, something I've never done in any show until now, and I fear that he's killing my love of acting. Please help.
