couldn't sleep last night

It is midterm time again, I don't understand why I still have midterms. I understood the purpose of midterms my first semester, because I won't lie, taking a law school exam is hard. It is mentally exhausting and the midterms were like practice, they gave me a small dose, a head's up on what the final would be like. The thing is, they don't really affect (or is it effect) my grade, maybe taking a 3.3 to a 3.4 or a 3.2, but not significant enough to matter and now they just feel like a waste to a perfectly good Saturday. I have one this afternoon at 3pm and I have studied really all that I want to study for it and it is 9:30am - but I feel guilty doing anything else. The problem is I studied too much yesterday and because of it I could not quiet my brain down to go to sleep last night. I went to class yesterday and then after class my friend Meaghan and I went through our notes for about four hours and made a skeleton essay outline, a template for answering essay questions...common procedure...it helps to organize my thoughts. Then I went home and slept for three hours until about 7:30pm and then I met Pranee back at the library to study some more about 9pm and we studied until 1am and we discussed the ends and outs of everything. Not only Con Law, but also our personal lives. So by the time I got home, my mind was in overdrive and so I read a little, a magazine called Relevant which comes with a high recommendation by me! So at about 2:30 am, still not tired, I turned out the light and turned on some music...but instead I just laid there until about 4:30 am thinking about everything and nothing and then I tried to concentrate on my breathing - but it was no help. Somehow I finally fell asleep, but it wasn't good sleep and I woke up at 7:30am a little pissed off that I was not still asleep. So I got up and went to Target, I like Target in the early mornings before anyone arrives and shopped for my brother's birthday present, because I fly out tonight at 10:30pm for his sweet 16!! I am now at school, I decided to look back through my notes one more time and that will hopefully make me tired so that I can go home and take a nap and then wake up for my final at 3pm. I hate when my body is out of whack...
