I don't use Facebook and I get by just fine. However, when I tried to switch to bing for a while, I could barely use the internet. Google is much worse than Facebook can ever hope to be.
Try startpage or duckduckgo for search. (The prior is essentially a proxy for Google).
Fastmail or protonmail to get away from GMail. One of the hard things about avoiding Google in email is that even if you switch, others you communicate are likely still there, so Google's still getting that information.
Conversely, when I use google, I frequently miss !w (search on Wikipedia), !i (search images), !a (amazon) and other "bang" shortcuts.
E.g., in Chrome: Settings > manage search engines > find Wikipedia > change the shortcut to "w."
