Ugh, one of my greatest regrets was how I left home.
I told my mother I was moving across the country, and I left 2 days later.
I am eternally grateful I apologized to her for it before she died.
She said it would have been difficult for her no matter how I did it, but that was part of being a parent, and she knew I'd wanted out since I was old enough to be cognizant there was an "elsewhere."
What was so hard was that because of how I did it, it felt personal, that I was trying to get away from her.
I assured her being away from her was one of the only things that made leaving difficult.
