I know what you are going through. I'm a college student and the same things has been happening to me lately. Stress can really freeze your brain. But it is a vicious cycle... you know?... THE MORE YOU WORRY SOMETHING IS WRONG, THE MORE YOU GET STRESSED OUT,THE LESS YOU CAN DO YOUR HOMEWORK, ...THEN SUDDENLY IT IS OVERDUE....AND THEN THERE IS MORE STRESS.... it goes on and on forever. Beileve me, I know. I think the important thing to do is find the cause of the original stress. You might need to go talk to a councelor. Tell him or her what is going on and maybe they can help you sort through it all. There is a free website called
http://goodtherapy.org that you can look at. It has a therpist search engine... you just type in the area where you live and the profiles of all the councelors in you area will pop up and you can look through them.
One more thing... have you talked to your parents about what is going on? Maybe they have noticed a change in your behavior that you haven't. Confiding in them might be helpful.
I hope you feel better and get your work done. You might just have to force yourself to get something done, even if its not perfect. Usually getting something done helps alleviate the stress and breaks the cycle. GOOD LUCK!
