Ignore leetcode style algorithmic issues for now. It sounds like you need to concentrate on the basics to get comfortable starting from zero and building from scratch. No shame in using libraries for complex algorithms (e.g. sorting or whatever), but getting comfortable starting with fundamentals is key I recommend finding an online MOOC uni/college compsci 101 type thing to teach you the basics of how to code in a structured way. It will lead you through how to actually breakdown and solve programming issues in a guided way. From there you can grow. You'll need to ease back the work hours to fit it in, but that will be good for you anyway! Good luck
