Twitching Arms, Poor Memory, Confusion and Paranoia?

I felt the same a while back and i know how you feel. You see everything in a dull way.What made me feel like this was i had just too much screwing up inside my head i needed to let it all out :s.You need to let it all out because those obstacles are blocking you. I let it all out by excersising , mostly beating up my pillow , letting myself fall onto my bed.
