i had the exact same symptoms as you op and was diagnosed with severe a.d.h.d when i was in high school. they gave me high doses of Ritalin but that shit didn't work just made me feel super drugged up and i was so motherfuckin burnt out after school i could hardly stay awake, and then had to go to martial arts and get my ass kicked a hour after school because i was so damn tired.

So one day I just stopped taking it. And focused harder, kept doing martial arts and it helped ALOT. Having a very disciplined state of mind can work wonders and motivate you to do lots of things.. Aced my course in college and am always on top of my game @ work, don't have any of the symptoms of "A.d.h.d" anymore. Keep my room / house / garage clean.. most of the time :P

You'll find if you stay organized it will help alot, keeping things clean and organized is one of the keys to success in life! Its all in your head.. Find ways to motivate yourself and work on your discipline !
