Genuinely interested: have you tried to spend a few weeks on an alternative?
I decided to try DuckDuckGo a few years ago. Not because it was obviously better, but to see if I could get used to it. After a few weeks, I had completely stopped falling back to Google when not finding what I wanted. I stayed on DDG for a couple years. Then same thing with Kagi: I just decided to try. It's been 1.5-2 years now and I'm disappointed when I can't use Kagi (which has my customizations, like some websites I ignore and some that I pin).
I guess my point is that it's not necessarily that you have to try something else when Google is unbearable. Maybe you can try something else and then realize (or not) that Google was not better.
