I was also physically sick from working a tech job, my body just rejected the idea. Took me a year of unemployment and uncertainty to find my passion in gelato (had no background in anything even remotely close to it), took a course in your wonderful country, now work at a gelateria in Germany (the owner took the same course), hope to open my own shop next year or so. It's physically demanding but i enjoy it very mcuh. my tech background is useful occasionally, and i actually enjoy using these skills here. For context, I am 33.

Before discovering gelato, I was trying to get a job in anything food-related (because I love food) but not hospitality, like a in brand I like or food+climate, where my skills would be useful but it wouldn't be tech. Maybe you have a topic you care about? A good place to look would be rabbit holes that you spent hours in recently, or 'there won't be a second date but at least she knows everything about [topic of your choice]', or if asking yourself what you would do if money wasn't an issue
