aaaaahh
I HATE IT.
I am too a compulsive procrastinator. I end up working myself to death because I have a scholarship and I have to get awesome grades, or else... But I still waste tons and tons of time doing everything BUT what I'm supposed to be doing.
Seriously, one time I wasted 3 hours online checking out new hairstyles. It was completely unnecessary but I felt compelled to do it. It is a serious disease.
I really have no idea how to help you. I have the same issue, and the only reason why I have kept my scholarship is because I pretty much gave up on sleep. Trust me, it is not a compelling solution.
