I had the same problem, here's what helped me. You should have some savings. Quit and take some time off to chill. Vegetate at home for a bit, travel a bit, and start doing a few leetcode problems a week. Soon you'll realize that you're not as terrible at them as before. I learned and switched to using python solely for interviews, and it's been a fantastic choice.

Start interviewing at a few places. You'll realize you're horrible at it. But keep interviewing. Doing leetcode doesn't compare to just having the experience. Figure out what you need to improve on, which algos you struggle with, Coding Qs, Behavioural Qs. Interviews become easier once you figure out it's just a matter of applying a few rehearsed algos and rehearsed answers in different ways. There's only so many ways to ask "tell us about a difficult problem/coworker at work"

Polish your resume up, talk to your co-workers and friends if you need help explaining/remembering what you did. Re-write it three times until it looks good.

If you do this, you'll have something better lined up within a few months and some time to decompress and time to renew your skills and confidence in programming. Whenever I quit, I always remember why i enjoyed programming in the first place.
