I'm in a similar situation. At my previous job, I burned out, and it led to some serious health problems. Now I don't even know what I want to do anymore. I was a software engineer for 20 years.
You're actually lucky that you can still exercise. I burned out so badly that I can't even handle any physical activity anymore. I really hope it gets better.
I'm even thinking about quitting programming altogether. But I love it so much that, at the very least, it'll always be a hobby for me.
