If you have savings for 1+ year and have been more than 10 years on the same company, you'll probably be allowed to get a leave. You could get a 3 months, 6 months leave or whatever you feel like, to think your next movement, explore options of what you would like to do, maybe experiment with new technologies and start some side projects to see if you still like coding but you don't like your work, or if you don't like coding at all, maybe experiment with other areas of work, even do some courses. Then go back from the leave refreshed, probably with new skills and a new view of things.

By then you might have a better idea of what kind of job you would like to do, so you can start looking for another job while you still have a job (which is always good in terms of negotiating power).
