Trying to Find Better
I worked at Amazon for three years. I watched a lot of people including some close friends go through exactly what is described on this site. There's an old group that I see a few times per year at each other’s house. Our conversations sound like we are all a bunch of war veterans who have suffered from PTSD from our time there.
It is possible for you to find a place in the company that isn't totally insane. My experience tells me that these places are few and far between.
The many Amazon folks I know and many others I have met around Seattle are always either looking for a new job elsewhere or else constantly switching teams internally to desperately try to find something better.
