Just pulled an all nighter for chemistry...... leaving for my final exam in an hour and a half

I feel like I haven't slept in days, I'm not allowing myself on facebook or tumblr or twitter. My entire grade depends on this one exam, and it's like that for 3 classes, I'm freaking out. I hope I pass with a decent grade :/ Going to take a shower now...... I still have 11 questions of this practice test to get through..... Tomorrow is potentially the longest day of my life...... A chem final at 7:30am, hopefully a nap right after, because a 5 hour calculus exam review after that, then cramming for my economics final monday morning. FUCK. MY. LIFE.
