I find that whenever I try and sit down and work on an essay, I find myself over taken with energy. I think derives from stress, but whatever it is it completely inhibits me from being able to sit still for more than a minute, and even when I am sitting my mind it racing much too quickly for me to be able to actually get any work down. It results in all my work being late, and that's proving to be pretty problematic. Any suggestions on how to help this?
