This reads a bit like a plea to Facebook for account restoration.
So it's two-fold: I want people to know they can get banned, at any time, for life, without much of a warning. And two: you might depend on Facebook more than you'd like to, so plan accordingly.
I really hate that I can't talk to James anymore. I didn't even bother to swap email addresses.
Hang in there. De-Zucking your life is a net positive.
