Anyone else stop all contact with their Mom?

My mother has been a controller and hasn't worn the pants in the family as long as I can remember. She has always loved saying cruel things to me, smart remarks and expects everything to be done her way or no way. To make a very long and painful story short, my mother has babysat each and everyone of my sisters children, for pretty much the past 35 years. My parents were in their late 70s when they started babysitting my sisters eight-year-old autistic son. The last few years my father's health has been declining and he has asked my mother to stop watching the grandson and have my sister find a babysitter, as it is just getting to be too much for him. But my mother refuses because she does as she pleases. I went through a divorce a few years ago and moved in with my parents to help them out financially, because my mother was always borrowing money from me and never paying me back. I have always been a daddy's girl, so when my father was diagnosed last August with cancer it shattered my world. And it has always made my mother mad that I was a daddy's girl, and she would make fun of me calling him "Daddy", because she always wanted everyone's attention and she did not always have mine. While my father was sick with his cancer, my mother was still babysitting my sisters autistic son every day and of course his needs were more important than my father's needs so whenever and my father needed anything he had to wait. I would try to help my father as much as I could, what there was something that I could not help him with. I would hurry home from work to see how he was doing, and I know my mother hated him getting the extra attention because some days she would completely ignore me. just a few days before my father passed he was sitting in his chair, before he was bedbound, and needed my mother to help him to the toilet which was sitting beside his chair but he was too weak to get up himself. My mother was babysitting the grandson and yelled at my father "oh my god, you just went! Well I am busy and you're just going to have to wait." My father was having diarrhea and kept begging my mother to help him until she finally slammed down on the table whatever she was doing and stomped out to help him get to the toilet. When my father passed away my whole world came crumbling down on me.The evening before he was laid to rest my mother was in a rather smart a** mood, so she decided to attack me and make fun of me for calling my father "Daddy" again. I was hurting so badly and to have her make fun of me was like a slap in the face, so I walked away from her.after the funeral I spent most of my evenings back in my room to avoid my mother and her attitude. But that did not keep her from coming back and telling me how I should be watching TV with her or going out to eat with her or spending time with her but to be honest I didn't want to be with her because of all the hurtful things that she has said and done to me and my father in the past.I would walk out to the house and hear her on the telephone talking to either my sister or her family telling them how I did nothing around the house, I didn't help her at all, and all I did was sit back in my room.I confronted her about that quite a few times, and I was crying as I explained to her how it hurt my feelings, but she never ever apologized to me. She would just deny it and walk away. Finally this April I moved to a different city, about 20 miles away, and did not tell her where I move to. I had to get out because, as my daughter told me and as I knew, I was on the verge of a nervous break down. My mother has called my cell phone twice, and whines about how depressed she is and how I should not have moved away because it was like another death in the family, and I have kept the phone calls short. She called me on my birthday and just gossiped and wanted to know what was going on with me and my children, which I don't tell her because it's just fuel for the gossip fire. After I talked to her that August day I blocked her email, and I blocked her phone number because all she does is give me anxiety and raises my blood pressure and says things to hurt me and I don't need that in my life. She has even called my son wants and emailed him twice, but he will not talk to her either. There is so much more to the story then I have space for on here, like my mother having an affair with my father's friend because my father was drinking after his mother committed suicide and my mother was not getting the attention she wanted from him sexually. My mother is still trying to contact me, as I got an email at work a few weeks ago which I ignored.and I also feel that with all the stress that I have been under that I was not performing like I should have at work, it was probably the reason I got let go two weeks ago. Many of you may judge me and think that is terrible that I want no contact with my mother, but I feel like a huge weight has been lifted off me and I'm beginning to smile again
