Need help training my quaker parrot?

I have a quaker parrot and she was given to us about a year ago. Her wings are clipped and she goes in and out of her cage and she has a bunch of toys she plays with and does her preening. When she came to us she had been abused and she doesn't like men. That is only part of the problem, the problem is that i go online and look for ways to train her but the thing is she is afraid of everything. I try and reward her for doing something right or good but she is terrified of the fruit or veggies and if its a toy, she only likes the toys that are hanging in her cage. If i put a g or carrot or anything that doesn't come with her food in her food bowl, she doesn't even go near it, i have to take out the fruit or veggie i put in so she can eat again. She has gotten a lot better since we got her, when i get near her she doesn't scream, she only screams if my hand is too close to her or her cage or if any man or someone who really scares her. I need help, i know this takes time and its been a year but i just want to see more progress. Please i need some really good advice or some help!
