What do you think?

It sounds to me like she needs some hauling time. As long as you are training her right, staying calm and continue to show her, in time she will come around. You said she has cross country'd, sounds like she is use to hurring over the jumps looking for the next. You may need to slow her down some, and get her to focus on the jump infront not 3 ahead. And I would not be humilliated, try having your horse turn left rather than turning the barrel!!!
