Those kinds of things always seem timed/planned by unknown forces...
I don't know if it makes it harder or not because I've never been without loving/supportive people around me. (Not often physically around me but consistently reaching out).
My wife writes similar notes to me somewhat regularly. They always sting. She's so forgiving, understanding, easy and loving.
Friends I have also realize when I'm isolating and write touching proclamations about how good of a friend I've been, etc.
Family is one holiday/b-day to another. Always positive, always loving.
Not one of them will ever really get it. They just have no direct experience.
My wife tho...while she would never accept ctb as a plan, she would understand. Still be crushed and maybe more tempted herself...but she's experienced painful depths and has considered it before.
