This year is awful for many reasons, but I think in the long run (and I hope this doesn't sound too trite), if you make it to the end you will be better off for it, no matter how well you did or didn't do. I've tried to put my finger on what makes it so bad. The stress would be number one I think, then perhaps the transient nature of any friendship formed during the year (I've made about 1000000000 five minute friends, and perhaps two or three real friends I talk to more than once a month) leading to isolation. For me it's the naging feeling that I will wake up at the end of the year, find myself turning 20, and wonder why I spent my final teenage year with my head crammed in a textbook. The saddest thing about this year is that any one of those things can trip you up, nearly every exam (Physics midterm = meh) is make or break, and if you screw up early when still finding your feet, it will change the course of the rest of your life and make it that much harder to get where you want to be.
