Acceptance, peace, forgiveness...these are all really, really hard things. Not sure why they have to be/feel so hard, but I'm just going to chalk that up to "things I'll never understand."
I have so respected my mother and her feisty strength for so many years. It is so hard to watch such a person fight on when you might hope that they could feel more peace. But it is what it is.
It is my hope for you that any coming limitations are ones you can accept and not feel rage over. I also hope you can get more of what you do want over coming years.
