I literally don't understand why you are still working.
Either quit or take short term disability. Why is this a question?
Pay for health insurance for the year, figure out where you want to live, and then once you have recovered, either you or your wife can go back to work for the sake of insurance if that actually ends up making the most sense, but don't worry about it right now.
Right now, you have more than enough money to do the smart thing, which is to not worry about any of that shit at the moment.
You are experiencing a medical emergency, so do the responsible thing and take care of it like a grown ass adult.
Thanks Malcat. My heart knows what's right, but my brain says otherwise. It's just such a large life event that I am afraid to pull the trigger. I did sit down with the wife tonight and we decided that I will turn in my 2 week notice tomorrow. Will see what happens.
Human beings have an idiotic bias towards trusting what they are currently doing more than the unknown.
It's idiotic, because a lot of the time that means trading and unknown risk (making a change) for a known 100% risk (continuing to do what's awful).
It means you ironically feel afraid of losing the "security" of what you know, even when what you know is literally killing you.
The fun part is that humans are not rational creatures, we are rationalizing creatures. People think they're rational, but for the most part, that just isn't supported by science. So what happens is that you have this reflex to hold on to what you know, and then retro-actively invent powerful rationalizations for why.
That's why I say to never give too much credit to the reasons you feel compelled to stay where you are. They're just cognitive noise, and they will disappear immediately once you make a change because they won't serve a purpose anymore.
What you are experiencing is very real, but the things that you tell yourself aren't necessarily. I *strongly* recommend you get some very good therapy through this, because you have a lot of trauma to work through, it doesn't just go away when you quit the job that caused it.
Focus on what matters. You have enough money so that work doesn't matter. That's great, no distraction. So now you can afford to do the responsible thing and take care of yourself.
It's time to TOTALLY reorganized your priorities. You've had a set of priorities that have guided you for years and lead you to this point, which has left you mangled. It's time to throw those out and start from scratch with new priorities, which will provide new guidance on your decisions.
I'm glad you are giving notice, because that's what a responsible person would do if their health and the well being of their family was their main priority.
Grab onto that and run with it. Start filtering all decisions through a priority framework that puts the physical and emotional well being of all of your family members first. What does that life look like? How do those decisions get made? I bet that looks very different from how you instinctively feel you need to behave from years of prioritizing career success.
Really take some time to reflect on the state that you past decisions have resulted in. Respect why you did it, because it produced financial Independence, and then respect those decisions even more by never EVER repeating them.
