I wish I had made that decision when I could. I'm over 20 years into software development and every few years I try to get out of it, but most places won't hire someone with professional experience because they're scared you'll quit, and that problem just compounds itself over time. Instead I now work software for a few years on, then take a year off. During the working years life is a real stress, constantly thinking about work stuff, even on my off-hours. I can only dream of having a job that I could just switch off at the end of the day. Or - better yet - a guaranteed basic income so I didn't have to work doing something that exhausts me so thoroughly.
You still can! You just need to find someone willing to give you a shot. If you're financially able to, definitely tell them your story and offer to work at a reduced "probationary pay" for some months to show you're dead serious.
I don't see a reason why any time is too late to get out. I was in software development and sysadmin field for about 15 years. Then started hand engraving (got quite good at it) and now I'm a full time CNC machine shop and growing steadily. Loving (almost) every day of it. Also went to college to study mechanical engineering. Of course being your own boss usually doesn't let you switch off at the end of the day, but that was just the choice I made for myself.
I believe I could get back to IT if I really wanted to, or needed to. Would need few months of getting up to date with all latest developments and living in the "land of the unicorns" I don't think getting well paying job would be a problem.
Look for work in an industry with demand. In US that would be electricians and plumbers. If you take the time to get certified, no one will doubt your sincere interest. I don't think anyway.
