Just be careful. Take a bit of time. Discuss on here whether you want to DA or fade away (go inactive).
The best approaches to either are markedly different.
DA? I would write to everyone I know just before the announcement an email about one A4 page long (no longer) with irrefutable back ups to the main reasons for my DA. Or not. It's up to you.
Fade? Keep your gob shut and your head down. Stand your ground but do not say anything other than "I'm going through some personal things right now which I cannot discuss with anyone." REPEAT ad infinitum firmly and politely. Walk away if they are persistent.
Best of luck and welcome!
