My 56 year old mother refuses to let go, calls, texts, wants to be everywhere I am and do everything I do. How can I gently get her to let go?

I'm 32 years old, I'm a survivor of childhood emotional abuse and neglect as well as physical abuse, which in turn lead me to have a low self worth and ultimately, lead to my decision to get married in my late teens (adult) of course. I married had children and this turned out to be a very toxic marriage, I'm now a DV survivor. I worked very hard to get some level of independence. However my mom has been my first abuser for years and not only that but she's made it nearly impossible for me as an adult not to need her, from trying to brainwash me that everyone that's not her is only coming in my life to destroy my life, to every single man on this earth is a Jeffrey Epstein she has an unhealthy obsession with predators, we all know they exist and I myself as an SA survivor I know what to look out for and the proper precautions to take, but this seems to be her way of keeping me from getting in a relationship or ever getting married again. I'm in no rush but I noticed she works extra hard to make sure I have no time alone that I always have at least one child with me and they have to report back to her everything. Im 32 and I still don't have a driver's license, where I live it's unattainable without someone kind enough to let you borrow their car and driving schools don't allow their cars to be used for the road test, it wasn't a priority for my mom to teach me when I was a teen, and my toxic ex husband refused to allow me to drive, so I've been in this decade long fight trying to get a driver's license on my own, Im unable to keep jobs or have any stability due to this and co workers quickly lose respect for me when they see me being picked up and dropped off by my mom and my kids all in the back of the car. I had one opportunity to buy a proper running car during the pandemic but because I was staying with her due to a move she begged and begged me to not buy a car, and unfortunately where I live from my knowledge you cant buy a car without a license I had no one to register it with. I'm really in the dark about car buying I try to figure it out but I have no help, but the fact she begged me to not buy a car knowing I'm a single mom made me question her intensions? I worked and worked over the years busting my a** on min wage jobs losing them due to transportation issues mainly, and my final straw was after my mom met me after work after I Uber'd home and she beat me with a heavy duty tripod upside my head striking me multiple times until I collapsed and that wasn't good enough she had my brother who very large in height and weight pin me down so that I couldn't escape then when I somehow managed to get out of it, she told him to go and get the gun to shoot me with(he didn't). All of this occured after a bad argument we had and I told her I was leaving and that I was taking the kids with me after she called social services on me and then lied and said the neighbor did it, and told several different stories, whatever narrative she tried to spin, and whatever response they had sent her into rage, but idk how true her story is, or if by me saying I was leaving and taking the kids , it sent her into a rage. I'm permanently traumatized 4 broken teeth later, she really made sure to try and disfigure me. the assault left me painfully hurt, confused and I had to resign from my job, we moved out a month later, fast forward it's been almost two years since that happened and me distancing myself trying to get my life in order, but a struggle with no access to transportation, I occasionally rely on her for rides or I'm forced to have to report to her if I use ride share which is rare, she is constantly trying to find opportunities to be a part of my regular daily life, using things that I would have normally said yes to out being necessity, but I will pay double on grocery delivery, I've been unemployed on snap benefits almost a year, all she talks about is me getting a job and her watching my kids or us going to work the same job togeth
