I would do turn on the forehands in hand with a dressage whip, getting her used to moving away from pressure. Push the butt of the whip into her side where your leg would go, if she does respond a little tap on her hand legs to tell her to move them.
Then move that to u/s. do TOF, it may be easier for her to grasp of you let her walk a small circle at first when you do it. then ask her to halt and do it.
Also, encouraging her to walk/trot forward and ignoring your head right now will help (as frustrating as it may be for you). Just keep pushing her forward, and keep your hips pointing where you want her to go. It might not be perfect but its better not to fight with her, it'll get better with time.
"The white horse moved like a dancer, which is not surprising: a horse is a beautiful animal, but it is perhaps most remarkable because it moves as if it always hears music."
