I disabled my FB account during the election run up. Continually, it amazes me how the temptation to go and reactivate my account reappears.
It sucks you didn't get a chance to do any house cleaning before leaving the platform. As for myself I became frustrated one night at the insanity and unreality of what people I actually know were saying. So I just pulled the plug and disappeared myself, not letting folks know ahead of time, just "poof" he gone. No housecleaning or goodbyes for me either.
There were several groups I belonged to that were good for meeting up for various activities or getting info on trail conditions (mountain bike trails). Also I had a bit of success with FB marketplace. Marketplace is the leverage point of temptation for me right now, as I've downsized and have stuff to sell.
Overall, being off the platform has been a positive, you can take solace in that many of us have found that to be so. You will be better off.
