Welcome to Virtual Hospice Nancy.
Such a trying situation and, as you quickly discovered, you are not alone. I see that you have already met Tracy (aka Worried Daughter) who is experiencing similar frustrations with her mother. I'd also like to introduce you to Glasslady001 and Cindie 46 who started these discussions.
It is hair pulling when someone you care about makes choices that don't make sense to us. I think you hit on a key point - acceptance. It is hard to let go of the anger. But as you point out, you want to make the time left a positive experience. You're on the right track, especially that you recognize that you also have to mind your own mental health through all this.
I'm glad you chose to share your thoughts with us. Bounce ideas off us, share the good moments and never hesitate to just blow off steam. It has to come out somewhere. You won't be judged here. We'll listen and support you.
