Dragon: just wanted to say I'm rooting for ya!! To me (and a lot of others, I'm sure!), what you're doing is EXTREMELY brave--it's never easy to stand up to your parents when you're getting told there's "nothing wrong". Fact is, if you know in your gut that something needs to change, GO FOR IT!! The fact that you want to change this will make change possible for you.

And don't let your dad get you down. He's probably having as hard of a time dealing with this as you are, simply because he feels responsible to some extent. I'd just give him time, and hope he comes around.

GOOD LUCK!!
