Self Improvement Made Easy

Many people may think this is dumb, but it's true. I'm addicted to procrastination. I even get headaches if I try to force myself to do something before the last minute. I'm now a junior in highschool, and it's really getting in the way. My report card has been my worst ever, and I can't continue to be hindered by this if I'm gonna get into college. So please, if you've been through this and gotten over it or you know anything that can help me, please let me know. Thank you.
No more comments like rokbonka's. I'd rather procrastinate than try and force myself to work through those headaches. And, I say force cause I get really easily distracted when I don't procrastinate.
