So some of the issue maybe ideas from this Eric guy and/or your mother feeling unstable with menopause

it might be best since it seems you are staying there for a while
is to possibly spend less time around her and/or be more careful what you say around or to her

with my mother, who I think is going through menopause, I'd found a slight combination of the two seem to help
if I spend less time around her, even if she kind of barges into my room a lot to talk, it reduces my chances of saying something stupid
also trying to limit how you talk to her may help, I have gone from long-winded conversations with my mother to very short ones when I can
some times a nod works or yeah okay or something short
I still talk to her some but mostly when she has something she wants to ask or say...
I started this because it was suggested to me and it seems that nearly anything I'd tell her became gossip to the people she is close to, it took me a while before I could do it but it helped me some

not sure if that will help or not
it just sounds to me you need to keep a little distance so not to make things worse or harder on yourself while you still live there
