Congratulations! I did the same recently. Facebook was the perfect destination for becoming mad and disappointed in the people I've associated with in my life. Not a productive task under any definition.
"At least the rest of my social media has a positive impact on my life," I jest.
Going to add to that, becoming disappointed in myself. It just seems to bring out the worst in us.
I do confess to still having Instagram, but I haven't had the toxicity experience there. I have successfully convinced the algorithm that all I care about is cute dogs and ads for mechanical watches :-)
