I've been riding for fourteen years, and have definitely had my experience with some brash trainers. I've met ones that yell, get frustrated, and ones that don't do either, but that I simply don't get along with. I think it's fairly common in the horse world (particularly with the english disciplines?)
That said, blatantly insulting you is out of line, and disrespectful. You are her client, and need to be treated as such.
More than that, having you jump higher than you are ready is downright dangerous. I would suggest finding a new barn, or this woman could break your desire to ride. It's only a matter of time before you don't find it fun anymore.
