I totally hear you about the walking on eggshells! I am now in my late 60s and my mother long since departed, but it's only now I'm seeing how her narcissistic behaviour has affected my life and most of the (bad) decisions I made. I was completely and totally controlled by her until I left home at 18.
She made decisions for me, chose my clothes, made me into her scapegoat so that I was always nervous and anxious, never knowing when she would explode in rage over the slightest thing. She also expected me to "make her happy" which of course was impossible, so I grew up feeling inadequate as well as everything else.
At some point I realised she would never, ever be satisfied, and whatever I did to try and make her life better was a waste of time.
And yet, and yet....like you, I sensed the frightened lonely child inside and was sorry for her. So eventually I decided I wouldn't cut contact but promised myself I would do only what was necessary as a "dutiful child".
If people believe her when she badmouths you, just know that most narcissists can be utterly charming and convincing when they want something, so you won't be able to put your side of the story. They are brilliant at looking after number one. It sounds as though you have friends and people on your side that know the truth so be thankful for that.
Maybe it's time to start thinking about gently but firmly laying down boundaries? I know the first time I said I wasn't going to listen to whatever tirade was going on and left, my heart was pumping and I was terrified. But the world didn't end.
Once you do it once, it gets easier. I think my mother started to respect me a bit and got a bit better. They do project a lot, so you, as a rational compassionate person, probably seems to her as a walkover because that's not how SHE would behave.
Remember narcissists don't see the people around them as sentient beings. Rather as lifeless mannequins with no feelings, there to service their needs. To her you are simply not a person as we would relate to another person, because she simply doesn't relate to anyone as we would understand it.
You don't undo a lifetime of abuse, either as the abuser or the victim, but if you can make her think you really don't care and are prepared to walk away, it might help.
