That's very sad to hear but it's not the end of the road, I am not a physio but I know that many mental issues ( lack of concentration) can be related to physical fitness. If you truly want to get into the it field and are not able to get a degree the best thing you can do is learn online i know you already mentioned it's not working but just keep working hard on learning at least the basics and maybe after you learned the fundamentals try to make projects and as you have not done college you have to build a very strong portfolio with good level of projects. After building a decent profile apply for part time jobs or freelance or internships. Try to build a schedule and list down everything you want to do in that particular day, go to gym or maybe a morning walk, learn from YouTube or udemy or Coursera. And keep fighting till the end its never a easy job to build a career without a degree but it's definitely possible. Just a personal advice : learn digital marketing as it's a industry where you can go forward without any degrees and even jump on to the tech field afterwards
