It may not be the end of your relationship.
What you are experiencing now is very similar to the problems I had with my mum. She was at exactly the same stage as your mum - still living on her own and thinking she was doing everything - showering, housework, laundry, shopping and cooking - when in reality she was doing none of it. She too was very angry with me and wouldnt let me over her doorstep. Yes, she often shut the door in my face. She also accused me of stealing from her, shouting at her and hitting her, whereas, in reality, she was the one doing the shouting! Social Services did nothing because she refused carers. I tried to get some in, but mum wouldnt let them in her house either. By this stage I was pulling my hair out with worry.
Eventually she had a TIA and ended up in hospital. From there she went to a care home and stayed there up to the end. It took her a couple of months to settle (she was constantly "packing to go home"), but she did settle and then she thrived. Her old personality returned (though not her memory), I became her daughter again (although she often got muddled as to the exact relationship) and her face would light up every time she saw me. She became a whole lot of fun again and I was able to take her on trips out to a cafe or garden centre.
This stage wont go on for ever, although it might take a crisis for it to change
