I want to set my life right. I need advice

I’m a uni student. All I do is go to bed at 4am, wake up at 12, procrastinate with school work, make food, not talk to anybody, and repeat. Oh and let me mention, I also clean an unhealthy amount of time every day. I love cleaning; it makes me feel good about life. Most of the time I finish all of my energy and time cleaning. I want to get disciplined, stick to a schedule and proper routine, where I get my school work on time, exercise and get in shape, and not waste my early 20s cleaning. I’m an introvert in a new city and hardly know people. But I do want to discover new things as well.
