What is my problem??

I am stressing MAJOR!! I am so mad at myself! I always do this. I have finals due tomorrow and I am just today really working on them! What the heck is my problem that I can not just start early and not be freaking out about them at the last minute? I hate that I do this. I really did try to start early, but every time I sat down to write...nothing. Not a thought would come to mind about the topic I am supposed to be writing about. I blog, check email, surf the web, read blogs, totally waste time! But work on my finals, oh no, I can't do that until the last minute and even now, What am I doing?? Blogging about how I am not doing my finals!! I don't know what my problem is!
