Need some help, opinions.

Lots of good advice here Jeff. A little "distance" between you and Mo would be good. What I mean is a new hobby or routine for you. Mo may come around and participate after a while?
I would also suggest help in some way for her, whether it's a therapist, doctor or nurse. Reach out. A stroke in conjunction with possible depression is something that any person would need help with.
Thanks for speaking up!
