Hi Donna,
My thoughts and prayers go with you on this venture. I hope it resonates a chord of acceptance with your mother.If she did her job properly, she should have had some inkling, long time ago.
I'm attempting to do the same to mine. Regrettably she is just starting dementia. Early days but you can see it happening. I know she always longed for a daughter, and indeed it would be truly the greatest gift I could ever give her. Her lifelong dream - mine too.
Keep in touch and let us know how you cope.
Be safe, well and happy
Lotsa love
Catherine
