I did the other way around. Went from teaching (university level) to FAANG. I could discuss for hours about the pros and cons of each job, but the bottom line is that I can't afford not earning that money. I'll save every single dollar I can from my SWE job and think about something else when I'm laid off, but I'm not leaving on my own.
You sound like a prisoner. No disrespect intended. It really sounds like you would be happier somewhere else. I wish you that you find that place soon.
