Yeah, there's all kinds of trauma that can happen with that sort of mind set. I'm sorry they can't open their minds.
AFAIK, episcopal, lutheran, maybe methodist are all inclusive, not exclusive. And if you can't go permanently, whatever, it's for you.
I hope you can get a scholarship. You know, there are all sorts of weird ones in the depths of the counselor's drawers. And there are a lot of schools that do horse stuff (our local A&M has a horse riding/judging team that I'm sure they do some scholarships for.

You're welcome.
