I just spent fifteen minutes having my officemates try to calm me down because I had a crying fit because I didn't finish my quantum homework (I have only a couple equations on problem 4) and both my physics classes are making me feel stupid. The worse part is that I usually feel like I get lectures -- but when I do homework, I'm all 'huh?'. Just homework... when five grad students can't get a homework set without fudging a few factors, i start to wonder.
