Hell Week

I'm just about finished my "hell week" at the U of A. Tomorrow I write my last midterm (of 6 this week) for the term. Thank goodness!!!
I'm so burnt out I can't even pretend to study anymore.
I have to say, before attending the geology program at the Uof A, I had not experienced a panic attack or had any problems dealing with exams, but now I can say I am a veteran:)
Dealing with hard core stress is something that I and my friends at school have had to learn to deal with. It can be hard though.
My friend called me this weekend while we were cramming for two major exams on Monday to tell me she was so stressed out she had thrown up six times that day. Not good.
I myself almost broke down in tears Sunday night because I was so worried about my exams.
I just keep telling myself that it'll be ok if I don't get that A I wanted, if I don't get accepted to graduate school, if I fall flat on my academic face and ruin everything, it'll be ok.

Monday was the a bad day for me. I had to write my Igneous Petrology exam (a class about igneous (volcanic) minerals) and my Petrogenesis (a class about diamonds) exam within a half hour of each other. My Petro exam was worth 25% of my final mark so I was worried. On top of that, when I woke up that morning, my cat's face had swollen up and I needed to call my sister to take him to the vet.
So after writing my exams, I rushed to the vet to see my cat. Three hours later, I left having gotten in an argument with the vet, been suckered out of $200 and my cat having healed on his own in his cat crate (he seems to be fine now thank goodness).
Worst day ever...

But after all that, my sister and brother brought me pizza and some movies and we all had a nice night. My stress started to melt away and I realized that in the grand scheme of things, tests aren't worth crying over or puking for; they're just tests.

But I have to say, it's hard finding that balance between trying to do your best at something, and letting that take away from the quality of your life. What amount of sacrifice is school worth? How highly should I value it? Right now, I'm acting like it's the most important thing in my world. Is it?
