You're not alone. I wasted my entire life - the prime of my life - as a JW... over 30 years. And I'm sort of going through the painful withdrawals now.
Be respectful with your parents, but not apologetic. Tell your parents you're searching for truth. If the religion of JWs is the truth, then what harm can your searching do it? Can't truth backed up by the Supreme Being stand up to a little scrutiny and verification? What do JWs fear about the stuff you're reading? Do they think the words have some magical quality that will put you under a spell? They're really just simple facts.
She also asked me to stop reading all the material I have been that "contradicts God's word"
Tell her you're willing to open-mindedly and reasonably discuss the issue if she will do likewise. If she says she doesn't want to hear evidene you have against her beliefs, then tell her it's not fair that she regularly presents evidence to others against their beliefs. Ask her how she knows that the material you've been reading contradicts God's word. What specifically contradicts God's Word? Make her be specific - no generalizations. JWs simply can't answer the tough questions, they don't have the answers they think they do, and they cannot defend the organization against its history of failed prophecy, craziness, deception, hypocrisy, propagandizing, etc. That's why they generalize and run from real arguments; they always want to be in control of any discussion.
Again, don't be apologetic and don't let her (or anybody else) be in control. Why should you apologize or feel bad for using your mind and searching for truth. Read her 1Jo 4:1.
Dear friends, do not believe everyone who claims to speak by the Spirit. You must test them to see if the spirit they have comes from God. For there are many false prophets in the world. -New Living Translation
Tell her that if she tells you not to test teachings, she's the one 'contradicing God's Word'.
When I say 'don't be apologetic', I'm not telling you to be disrespectful. Be calm and in control of your emotions. Dont' get mad. Be reasonable. Maybe you will slowly win them over.
The sun and the wind argued one day over who was the stronger. They decided on a way to settle the argument. They looked down and saw a man in an overcoat. They would see who could get the man to take his coat off. The wind went first. He huffed and puffed and strained, but the stronger the wind blew, the more the man buttoned up his coat and the stronger he held on to it. Finally, after the wind was exhausted, the sun took his turn. He simply smiled and very calmly and slowly shone on the man until... well, you can figure out what happened.
The point is: Be like the sun, not the wind. If you beat your parents strongly with words, they will just hold on tighter to their perceived truth. But if gradually expose them to sound reasoning, you might get them to 'take their coats off'.
