I am sorry. It is so hard.
I get a lot of feedback that I should basically let her figure things out on her own. Maybe I am over the top with codependence but I don't think that's it. My mom loves me and I don't think she means to hurt me -- she just copes poorly.
I am going to encourage her to get help and hope that she does.
Thanks again for your insight.
No worries.

One more thing ...when i was participating on the Aspergers/Autism forum, I read and participated in a thread put up by an older Aspie/Autie, who was writing about how those troublesome traits actually get worse with age. Other's quickly added agreement to this sentiment.
It is, unfortunately, proving to be the case with my folks.
Myself, I don't have the energy for "masking" or any, avoidable socializing, anymore, unlike when I was in my 20's, and 30's but, I am committed to making the most of any level of neuroplasticity at my disposal, but, still, I find myself wanting a very quiet life.
If you do get to move closer to your ma, it might be that she's totally resistant to change, but, if it's at all possible to encourage her to challenge her capacity for poly vagal recovery, via safe and supportive socializing, or any kind of theraputic support, it will, surely, mitigate the cognitive and social capacity decline somewhat.
My dad has acknowledged his Autism/Aspergers, but won't really do anything beyond acknowledging that it's a thing. He's a churchgoer but due to lockdown that's declined this year. This year of lockdown he's declined hugely, from what my uncle's said.
I've been on the phone to him, but his calls have dropped off, considerably and I've rung him a few times myself, which I NEVER used to do. I'm pretty hopeless, in many ways, as a family member
My own personal thoughts and feelings on the matter is that we (Auties) need quite a bit more patient and considerate support, especially as we age and, ideally, when we are young. If we give up on working to expand our capacity toward socializing, due to the sheer exhaustion, and fraught nature of such, lack of opportunity, and other's lack of efforts toward inclusion, our brains atrophy rather more pronouncedly.
I guess what I'm trying to say is that it's likely that you will have to put in a large amount of the effort into prying your ma out, and her capacity has, likely, already diminished considerably, due to the Autism-brain-aging propensity and habitual rigidity that is a key feature of this condition.
It's kind of unfair, as we (Auties) don't mature, emotionally, particularly on par, at all, without tremendous efforts and supports, and then, when not "working the neuroplacticity and polyvagal repair mechanisms" with concerted attention and efforts, we rapidly degenerate in social and neural capacity.
