Me too on the sympathy, that is really a horrible loss... especially to happen during the roller coaster college years.
I am in a similar boat with my gpa from UG Yale. Had to take some time off. Was an ED of a nonprofit for a year as an undergrad and some other personal issues came up that killed the gpa. I don't think lsat of 170 is really enough to make me a splitter. If i don't get off the waitlist, I will retake with more prep. Good thing is that this week my boss agreed to keep me on with more limited hours if I get into PT (i originally applied for ft). With a 10% salary reduction. So I've still definitely got my fingers crossed. I think there are going to be really cool and interesting/challenging people in the PT program. My background is as an organizer. I've also done some policy work.
A 170 LSAT certainly inducts you into splitterdom. That's a great score (almost) anywhere! Congrats! and good luck to you.
