Ahh Lindsay!! That sucks. But it's just a semester, 4 months. Not that long, you can do it. You kicked massive butt last semester, you can do it again. As for the class with the mean prof, remember to try not to let it get to you. Besides, I"m sure everybody else if thinking the same things about him so the only one he's making a fool out of is himself. Really, you have the high path there.
