Well, my dear, I'll simply wish you luck then. You're going to need it.
I hope that she doesn't hurt you too seriously when she finally makes contact with a kick or when she finally walks right over the top of you....and she will if you don't get a handle on her.
Also, I strongly suggest you watch some real horse interactions at liberty in a pasture. Watch the alpha and see how they respond to an underling horse that doesn't back off when they are warned with an ear pin. They get the crap kicked out of them...but they never end up scared of the alpha horse.
I wonder why that is?
A good horseman learns to treat horses the same way a firm and fair herd alpha does. They learn to distinguish when a horse needs a correction and when they don't and and they don't overdo it. Where horses start getting fearful of humans is when the HUMAN doesn't know how to apply the correction correctly and either overdoes it or times it wrong.
