It's a lovely question, amillion! The answer's complicated. She feels what I would like my mother to feel - really, she does. But there's something missing between feeling and acting, in her case.
I finally got this during a family therapy session in rehab. The facilitator asked family members to tell the group how their addict's behaviours had hurt them. The other families had stories of robbery, violence, fraud, sexual abuse: crimes, basically. Mum told the group, passionately, how she couldn't sleep for worrying about me! My crime against her was that SHE worried about me ...

But, yes, she really does worry and, following many delicate talks, has some comprehension of why I'm angry that she tolerated my father's abuse. Her gestures are the only reparation she knows how to make. In the first year of this phase, she offered fairly crap gestures (cast-off clothes and half-eaten food, for eg!!) and I rejected them. Now she gives me nice 'mummy' things: decent food, home-made jam, £20 cash. As I need these things and understand her motive, I accept them gratefully.
One thing that I really, really want is people to help me sort my house out. A 'normal' family could fix this in a weekend. I have asked each member of mine, more than once, and they won't. They take me out to nice restaurants instead - on days of their choosing. [shrug]
