Keep allowing her to trust you, make her feel good by finding those spots on your body that you can rub and relieve any pressure or soreness.
My horse loves his withers being rubbed gently, along with his neck at the top. Some foals love the top of their tail (be careful!) and above their hips. Find those spots and get her to relax, slowly (not not too slow that you seem like you're pouncing) work towards her ears, taking your hand casually away before she reacts. Work on lingering there as long as you can before you get a reaction.
Good luck :)
