Have you considered a technical school? Many jobs are hands on, and pay well, but require some amount of training. I don't know how the educational system works where you live, but here you can get a technical school degree in 1-2 years in an area like electronics, nursing, drafting, etc.
If you really decide you need to stick with school, I agree with the medication option. Also, you can get almost any book in print on a recording if you have some sort of documented learning disability (from the society for the blind). I haven't looked, but I imagine those books on tape could be available even without a documented problem. You can get on a stationary bike, or treadmill and listen to your books, instead of reading them.
There is also no shame in just deciding to get a job and work for a living. I believe very strongly in higher education, but if you are not motivated, you are not going to do well, and it would be better to get on with your life.
