What could I do to make me less lazy?

You could quit school--it sounds as if you probably aren't getting anything out of it, anyway! Get a job at whatever you can get with your level of education and try living on that level of income. Know that that's where you'll probably be for THE REST OF YOUR LIFE, without higher educational level. If this doesn't motivate you to return to school and dig-in, then forget it. Some people don't get motivated until they are married, and/or have children to support. It's usually a case for most people that we either get motivated to improve our lot in life, or drum along at an uninspiring sub-level in life and just drift! There is always the Community Mental Health Agency, if you're old enough--or ask your parents, if you're not old enough, to pay for out-patient therapy to find out the core issue. It could be anger that has been suppressed against parents, etc...many things, really.
