Pick up a hobby project. Anything you like, don't tie it with money or earnings. Just something that will give you joy and let you stop thinking about everyone and everything else. If you won't like it, find another one and try again in a few months. You have access to the largest library in history of the universe, university majors are nothing compared to that. After focusing on it for some time you can share it with the world (for example Show HN), describe the process.
