Hello Carrie Anne,
I have spent many years in a similar situation. When I was in college, I acted out to the point of getting myself institutionalized, largely because I couldn't bear my relationship with my mother. That was 20 years ago, and I've learned a lot since then, but I just wanted to let you know that I may understand how deeply this can cut.
But I think the key is not to let it define you. Whether you have anything to do with your mother or not, you can go through life letting her win if you keep her in the driver's seat. How much of your mental energy do you spend on her? How important is she in your thought processes and your life? It sounds like she still occupies a lot of your mental space, so talking to her or not talking to her is rather beside the point.
I hope you keep posting and telling us more about yourself. Who are you, apart from and beyond your mother? What do you like? What do you want? I think the most important thing therapy has taught me is that there's no magic "freedom" bullet, but the important thing is to forgive and cherish yourself just for being yourself. In that way, you can start to live by your own rules and standards, not your mother's. You can reclaim your mental space, and learn to feel at home in it. And if you do that, you will be able to reach a final decision about whether there is room for her in your life or not.
Rather than reading, I hope you keep writing. There are good books, but in my opinion there is no "essential" book. The most important thing is not to absorb what a psychologist says but to learn to listen to the voice inside you that whispers, "I know why I am here, and it is not to be my mother's whipping girl." Eventually, that voice will gain force and volume, but only if you let it speak. So tell us more about yourself, your history, your desires--anything you want. But speak it, and keep speaking it until you learn to listen to it.
I wish you peace, and I hope we keep hearing from you.
