First, declawed kitties are very sensitive and even sometimes in pain because of the declawing.
You can make sure she has litter that does not hurt her pads, even if it means going to shredded newspaper. Then just give her time, let her hide if she wants to, sit down near her hiding place and read a book aloud to her (softly) Take some pounce treats or other goodies and set them in a circle around you and just see how long it is before she comes up to you. Let her come up to you, if she starts towards you don't make any sudden moves, don't look her in the eyes, just keep reading, or talking or whatever you are doing quietly. It may take some time for her to trust again, but my thinking is she is distrustful of humans because she has been hurt by them (declawing is so unneccessary and painful for cats) It is like someone ripping off all your fingernails under anesthesia but when you wake up it still hurts. I know you did not declaw her, but I am just letting you know how it might be for her. Just give her time, give her lots of good food, a soft place to sleep at night, see to her needs and change her litterbox contents. One declawed kitty I rescued years ago was so sore, I had to resort to using packing bubbles in her litter box. It was the only thing she could use and not feel pain. She would use the regular litter at first, but she also would cower and hide, and until I caught on that the litter was bothering her, she was as elusive as a ghost.
