If she was becoming unsafe in her home maybe better now she is in full time care?
It was somewhat of a relief when my mother went into care, didn't have to worry about her falling any longer. Travelling to help in her home. Caring is hard work. Can lose oneself if not aware.
Time now to become "free for life."
No need to drink over it. Celebrate.
I would not forego sobriety for anything. Nothing I can think of at anyrate.
